Mr. Mooney is an amazing attorney. He will be there for you in all aspects of the case. He’s empathic with you as the client and also is giving the best legal advice there is to offer. Mr. Mooney is very intelligent on the law and on how to apply it in the court of law. Through my case with him, he was very helpful and worked hard for countless hours of going through multiple pages of discovery and video. Due to his knowledge and hard work, ultimately the case led to the most favorable outcome and an entire acquittal was reached. If you’re unsure whether to retain Mr. Mooney because of financial purposes, I will just say this … I would rather have my freedom and be broke than not have my freedom and be rich. Interpret it how you want but Mr. Mooney is amazing and one of the best if not the best at what he does and will do whatever it takes to receive the outcome you desire.

Frequently Asked Questions About Law Offices of Thomas C. Mooney
What is a homicide?
When most people think of the word homicide, they usually automatically think about murder. While it’s true that murder is a form of homicide, it’s not the only one. Homicide is a broad term that refers to one person causing the demise of another person.
A homicide can be lawful or unlawful. It encompasses both manslaughter and murder, which are examples of unlawful murder. Lawful homicides include events, such as self-defense.
What could happen if you accidentally kill someone in self-defense?
Defending yourself can lead to unexpected and serious consequences. While Maryland law recognizes your right to self-defense, it will also hold you accountable for your actions.
An accidental death during self-defense is not a simple matter. It involves complex legal principles and potential criminal charges. If you ever find yourself in this dilemma, knowing what could happen could be a good way to prepare.
What does Maryland law say about self-defense?
Maryland’s self-defense laws stem from common law principles rather than specific laws. This can make it hard to understand your rights and responsibilities. Here’s what you should know about self-defense in Maryland:
Reasonable belief of danger: You must believe you’re in immediate danger of harm
Proportional force: Your response should match the level of threat
Duty to retreat: You must try to escape safely before using force if possible
Castle doctrine: No duty to retreat exists in your own home
These principles guide how courts and prosecutors interpret self-defense claims. But when an accidental death occurs, the legal landscape becomes much more complicated.
How do reckless endangerment and reckless driving differ?
In the eyes of the law, anyone who speeds up and disregards the safety of others on the road is often a serious threat to civilian lives. This reckless behavior can lead to severe legal consequences. Depending on the circumstances, the defendant may contend with reckless driving or reckless endangerment charges.
Reckless endangerment is not the same as reckless driving. While both involve risky behavior, reckless driving and reckless endangerment differ in several key aspects, such as:
- Intent: Reckless driving implies a disregard for safety. Reckless endangerment involves a conscious disregard for human life.
- Scope of harm: Reckless driving often involves traffic violations. Reckless endangerment involves more egregious behavior.
- Legal classification: Reckless endangerment is a type of assault. Reckless driving is typically a traffic offense.
It is important to note that these charges often overlap. If someone suffers injuries, prosecutors might charge you with both for the same incident.
Is injury necessary for a Maryland assault charge?
Assault does not always involve injury
The definition of assault in Maryland is somewhat circuitous. Assault charges may relate to allegations of assault, battery and also assault and battery. Assault involves putting another person in reasonable fear for their own safety due to a potential imminent physical attack. Battery involves non-consensual physical contact.
Frequently, situations that lead to assault charges do not involve severe injury to either party involved in the altercation. In some cases, the defendant may not have made physical contact with the other party at all.
Given the definition of assault, injury is not necessary for the state to prosecute someone successfully. All that is necessary is proof of direct threats or inappropriate and unwanted physical contact. Someone slapping a server on the buttocks could constitute assault, as could grabbing another person by the collar of their shirt. Actions intended to intimidate others or to offend them can lead to assault charges under current Maryland statutes.
Rather than focusing on the outcome of the incident, defendants may want to explore what led up to the incident. Many scenarios that look like assault are actually cases of self-defense. The other party may have made physical contact first or uttered a credible threat against the person facing criminal charges.
Reviewing the state’s evidence and the situation that led to an arrest with a skilled legal team can be beneficial for those accused of assault in Maryland. Every case is unique, but many defendants can avoid a criminal conviction with the right defense strategy.
What is involuntary manslaughter in Maryland?
Anyone who’s facing an involuntary manslaughter charge in Maryland should ensure they understand a few specific points about this charge. Involuntary manslaughter involves killing someone by criminal negligence or recklessness. Interestingly, assisting a suicide is classified as involuntary manslaughter in Maryland. It carries up to a year in prison and is a felony charge.
One form of involuntary manslaughter that some people may be familiar with is vehicular homicide. This occurs when someone is killed because a driver isn’t driving safely. Maryland criminal laws specifically address these types of vehicular manslaughter:
- While under the influence of alcohol
- Criminal negligence
- Gross negligence
- While impaired by a controlled dangerous substance
- While impaired by drugs
- While impaired by alcohol
With the exception of vehicular manslaughter due to criminal negligence, all those charges are felonies. All of those charges carry the possibility of up to at least three years in prison. Some have a maximum penalty of five years and others carry up to 10 years.
How is second-degree murder different from similar charges?
There’s often some confusion over different homicide charges. For one thing, people will assume that homicide and first-degree murder are the same. But there are actually many types of homicide charges that may apply differently from case to case. Every case is unique and deserves a unique defense.
Specifically, there’s a charge in Maryland known as second-degree murder. How is this different from similar charges, such as first-degree murder or manslaughter?
How it differs from first-degree
For first-degree murder, the person typically has to plan the event in advance. They must have the intent to take someone else’s life. Usually, the authorities are looking for evidence that the event was premeditated and then carried out on purpose. This is the most significant homicide charge someone can face and could result in everything up to life in prison.
How it differs from manslaughter
Manslaughter is similar to second-degree murder in that it wasn’t planned or done intentionally. But there are other factors showing that this isn’t how the accused person would normally act. For instance, perhaps they just reacted in the “heat of passion” and did something surprising and out of character. It is still illegal to take someone’s life, but this is much different than doing so intentionally.
What violent crimes warrant life imprisonment in Maryland?
Violent crimes are offenses that involve the threat of force. Assault, robbery, sex crimes and homicide are only some of the most common examples of these crimes. As a Maryland resident, it is crucial to recognize the gravity of these wrongdoings and their legal repercussions.
In Maryland, judges may sanction repeat offenders of sexual crimes with a lifetime in prison with no possibility of parole. This offense involves engaging in a sexual act with another by force or the threat of force. Initiating sexual acts without consent from the other party is also considered a sex crime in the state.
Kidnapping victims younger than 16 and committing sexual acts with children 13 years old and younger may also lead to life imprisonment. Offenders of this type of crime may not request parole.
Parole allows convicted individuals to spend the rest of their sentences outside prison. However, they must follow a set of behavioral conditions.
Child abuse and murder in the first degree are examples of offenses in which you may get life imprisonment but with a chance for parole.
Murder, manslaughter and homicide: What is the difference?
1. Homicide
Homicide is an umbrella term that refers to any act that ends another person’s life. Homicide isn’t always a crime. For example, in a situation where self-defense resulted in the death of an aggressor, the act may be considered justifiable.
2. Murder
Murder is a form of illegal homicide, which can be further divided in terms of degrees:
A premeditated, deliberate and willful act is first-degree murder. The first-degree designation also applies to death resulting from specific felonies, such as murder, rape, robbery or burglary. The designation can also apply to a homicide that involves the use of poison or lying in wait for the victim.
A conviction of murder in the first degree typically results in the most severe penalties, including life imprisonment without the possibility of parole.
Second-degree murder refers to homicides that are intentional but not premeditated or planned. It signifies a malicious intent to kill or inflict grievous harm, but there was no forethought or premeditation. The penalties for second-degree murder are less severe than for first-degree but still significant.
3. Manslaughter
Manslaughter is characterized by the lack of malicious intent. It can be categorized into two types:
Voluntary manslaughter occurs when a person intends to harm someone but not to kill them.
Involuntary manslaughter happens when a death is the unintended consequence of an individual’s reckless or negligent behavior. This can include actions taken with a blatant disregard for human life, even if there was no intent to kill, such as vehicular homicides where the driver was operating their vehicle under the influence of alcohol or drugs.
Assault vs. self-defense: What’s the difference?
Cases of assault involve intentionally causing someone else to fear for their safety. It can involve physical actions, threats or even gestures that create a reasonable apprehension of harm.
Several elements must be present to be arrested for assault. These include:
Intent: The perpetrator must intend to cause fear or apprehension in the victim.
Reasonable fear or apprehension: The victim must believe they are about to be harmed.
Immediacy: The threat of harm must be immediate rather than something that may happen in the future.
Self-defense, on the other hand, is the legal right to protect oneself from imminent harm. It allows individuals to use reasonable force to defend against an attacker. The use of force must be proportionate to the threat faced and cease once the threat subsides.
Elements of self-defense include:
Imminent threat: The potential harm (or threat of this) must be present and immediate.
Proportionality: The force used in self-defense must be proportionate to the threat faced.
Reasonableness: The response to the threat must be considered reasonable under the circumstances.
Without these elements in place, an instance of perceived self defense can lead to criminal charges.
How could you contest assault charges?
Understanding possible defense strategies is essential. Here are some you might use:
Mistaken identity
Let’s say the police charged you after breaking up a bar room brawl or an incident at a local festival. There may have been a lot of people involved or in the vicinity of the incident. The police may have made snap decisions and erroneously led you away in handcuffs. Perhaps you were present, but all you were doing was watching or trying to break the fight up – neither of which is a crime.
Alternatively, an eyewitness might have named you as an assailant, perhaps the alleged victim themself did – but people often identify the wrong person. Sometimes, they do so intentionally, as revenge for an earlier incident or to save themselves from getting the blame.
A breach of legal procedures
The police must follow guidelines when interviewing and arresting people. If you can show they breached these before or after the arrest, a court might decide that the evidence gained is inadmissible in court.
Self-defense
You are allowed to harm another person in specific cases where doing so is critical to your safety, that of another, or perhaps even the safety of a property. You’d need to show your reaction was reasonable and that the threat was real and immediate.
With appropriate help, you can determine if one of these or another defense strategy could work in your case.
Why can’t you fly with marijuana products?
Even though you can legally buy marijuana products in Maryland, as long as you are at least 21 years old, there are still many restrictions on what you can do with them. For instance, you typically cannot fly with them, at least on commercial flights. This is true even if you made a legal purchase at a dispensary and you have the receipt.
What makes flying illegal is that marijuana is still restricted at the federal level. When you fly, you cross state lines, and this means that federal law takes jurisdiction. You also may be flying into a state like Texas or Georgia, where recreational marijuana products are still illegal. So flying can put you in violation of the law on numerous levels, even when you did not break the law while making the initial purchase.
What Qualifies As Illegal Drug Manufacturing?
Under Maryland law, drug manufacturing encompasses a range of activities related to the unlawful creation of controlled substances, including growing, producing, compounding, converting, processing, preparing or simply possessing the necessary materials or equipment with the intent to manufacture drugs. Even preliminary steps toward drug manufacturing can result in serious charges.
Drug manufacturing charges in Maryland can vary depending on the circumstances, but they often include possession with intent to manufacture or distribute, operating a drug factory and conspiracy charges. The potential penalties are severe, with sentences ranging from several years to decades in prison, along with substantial fines. Many drug manufacturing offenses carry mandatory minimum sentences, leaving little room for leniency without skilled legal advocacy.
The type of drug allegedly being manufactured can significantly impact the charges and potential sentences. For example, manufacturing methamphetamine or crack cocaine is treated more harshly than manufacturing marijuana under Maryland’s laws. The quantity of drugs involved and the presence of aggravating factors, such as manufacturing near schools or involving minors, can also lead to enhanced penalties.
What Is Drug Possession And What Is Possession With Intent To Distribute?
Drug possession means knowingly having an illegal controlled substance on your person, in your car or anywhere you have control over it. On the other hand, possession with intent to distribute means having controlled substances while intending to transfer control of the drug to someone else, as inferred from circumstantial evidence such as:
- Large quantities of the drug, beyond what is likely for personal use
- Packaging materials that could be used to divide up the drugs for sale
- Drug paraphernalia that could be used to measure drugs for distribution
Even if drugs are not being actively sold or distributed when seized, the circumstances can lead to more serious charges.
How will the DUI/DWI conviction affect my future?
A DUI/DWI conviction in Maryland may impact your future in the following ways:
- A DUI/DWI conviction will appear on your criminal record, affecting employment opportunities, housing applications and professional licensing.
- Maryland imposes strict penalties on driver’s licenses for DUI/DWI convictions depending on how serious the offense is and your prior record.
- A DUI/DWI conviction can significantly increase car insurance premiums.
- Fines and court costs can create a financial burden.
DUI/DWI charges carry significant consequences that should be arguably treated with utmost legal interventions.
How will a DUI/DWI impact my ability to maintain my driver’s license?
If your blood alcohol content level is .08% or higher, your license will be confiscated immediately and can be suspended for six months. Subsequent offenses or higher BAC levels can lead to more extended suspension periods or revocation of your license. You may be able to retain your driving privileges for work or school, but only through prompt legal action.
Maryland has very strict rules around DUI/DWIs – what are they?
The Maryland legal limit for driving under the influence is a BAC of .08% or higher. But, if your BAC is between .07% and .08%, you can still be charged with the same offense.
Maryland also has an “implied consent” law. This means that by operating a vehicle on public roads, you have implicitly consented to a chemical test. Refusing such a test can result in an automatic license suspension, even if you are ultimately not convicted of DUI/DWI.
