Drug Crimes

Attorney David J. Grimaldi has successfully defended numerous clients accused of drug offenses in both state and federal court. From major drug trafficking cases involving kilograms of narcotics to smaller charges of possession for personal use, Boston drug crimes lawyer David J. Grimaldi has obtained excellent results for many clients in courts throughout Massachusetts.

Drug charges can carry significant and long-lasting consequences upon conviction, including mandatory minimum prison sentences, extensive probation terms, drug treatment, suspension of a driver’s license, job loss, deportation, and other serious ramifications. If you are charged with a drug offense, you should obtain a successful criminal defense lawyer experienced and skilled in obtaining the best results possible.

When you are charged with a drug offense, your attorney must know how to analyze the case and uncover any unconstitutional or illegal searches that may have occurred. If the police or the government seized evidence illegally, including drugs, the Court can suppress or “throw out” the evidence after your lawyer files a properly argued motion.

Every case is different. Sometimes the police searched a car during a traffic stop without sufficient reason to do so. Sometimes the police failed to obtain a search warrant when one was required. Sometimes the magistrate or judge who approved a search warrant did not actually possess the information necessary, called “probable cause,” to issue the warrant in the first place. Sometimes the police officer, detective, or agent who prepared the search warrant included false or misleading information that unfairly led to the issuance of the warrant.

In all of these instances, your lawyer must properly identify these legal issues and argue persuasively to the Court to suppress or “throw out” the drug evidence that is central to the government’s case.

Attorney Grimaldi has successfully moved to suppress drug evidence in cases involving heroin, cocaine, crack-cocaine, marijuana, and prescription pills on numerous occasions. By suppressing the evidence, Attorney Grimaldi also won dismissal of the charges.

A common feature in drug cases is police use of “confidential informants,” also called “confidential sources” and “cooperators.” Many times, confidential informants have criminal records, were recently caught committing their own crimes, and are now “cooperating” with the police or the government in an effort to avoid prison. These confidential informants are particularly untrustworthy and have significant incentives to lie and set up other people for their own personal benefit. Even worse, the police often rely on cooperators without doing sufficient background investigation into their personal lives and histories of deceiving others. Your lawyer must know how to investigate confidential informants and, as appropriate, expose them as having lied about you in an effort to save their own skin.

In federal cases, the government sometimes uses the Federal Wiretap Act, 18 U.S.C. §§ 2510‐2522, also known as “Title III,” to intercept phone conversations, emails, text messages, and other communications involving individuals under investigation. Capturing a person’s voice on an intercepted phone call can obviously be very useful evidence for the prosecution. If the government used Title III intercepts in your drug case, your attorney must know all the ways to suppress and exclude that evidence in your case.

Even without a warrant, the police sometimes search for evidence in personal items, like cell phones, claiming that the particular circumstances justified the warrantless search. Boston drug crimes lawyer David J. Grimaldi has successfully moved to suppress evidence from police searches of a client’s cell phone.

In some cases, the police overstate their case against when seeking drug charges against a person. In such cases, your lawyer must know how to attack the complaint or indictment in a persuasively argued motion to dismiss. Attorney Grimaldi has successfully moved to dismiss drug trafficking charges by proving that the police misled the grand jury when the case was originally charged.

In some cases, drug analysts or chemists in Massachusetts have committed misconduct in performing their duties, including lying about test results on their drug certification documentation and even consuming the very drugs they claim to be testing. Your attorney must be ready to uncover this type of systemic abuse sometimes imbedded inside the criminal justice system itself.

On occasion, the best defense is to show the Court and the prosecution that you are serious about getting clean and leaving your past life behind. If you are in the Boston area, an experienced drug crimes attorney can help you obtain the drug treatment that is best for you, help you navigate your relationship with your pretrial services or probation officer, and advocate for you persuasively before the judge.

Attorney David J. Grimaldi has successfully defended many clients charged with various kinds of drug offenses, including heroin, fentanyl, cocaine, crack-cocaine, marijuana, prescription drug, and many other types of drug offenses.
