Criminal Defense Attorneys Practice Areas

Our lawyers have defended countless persons facing DWI charges. A winning DWI defense begins by questioning the officer’s decision to make a DWI arrest based on coordination exercises designed to fail, outdated breath testing technology, and problematic blood testing procedures.

Defeating DWI Field Sobriety Exercises

Officers are trained to administer field sobriety tests in accordance with specific standards. The problem is, officers often fail to follow their training. During a stop, standardized procedures are replaced by the officer’s self-fulfilled DWI prophecies. We have a DWI Houston criminal defense Lawyer who is certified in field sobriety exercises and can determine if the tests were administered properly.

Defeating DWI Field Sobriety Exercises

Every DWI Houston criminal defense attorney should understand and be able to explain both spectroscopy and chromatography, the science behind the chemical tests. Many factors can cause a reported alcohol content to be inaccurate, and our lawyers will discover the root of the false result. Call us to learn how, together, we will fight the DWI.

Drug cases are not as black-and-white as one may think. Our drug attorneys will force the prosecutor to prove all elements of their case.

Unlawful Drug Search, Seizure, & Arrest

Criminal drug charges are often the result of unlawful police actions. Amongst criminal defense attorneys this is known as fruit of the poisonous tree. If the officer in detaining, searching, seizing, or arresting you violated your constitutional rights, then any evidence obtained is considered fruit of the officer’s unlawful actions. This evidence is inadmissible in court and in most instances your drug attorney will get the case dismissed.

Possession – Is it a Drug?

Drugs are broken down into penalty groups. Penalty Group 1 and 1 -A consists of cocaine, heroine, opium, oxycodone, and acid, amongst other. Penalty Group 2 is hallucinogens, ecstasy, and amphetaimines, amongst others. Penally Group 3 is valium, xanax, and anabolic steroids, amongst others. The punishment range depends on the type and amount of the drug. Sometimes lab testing reveals the substance was in fact not a drug at all and as your Houston criminal lawyer we will demand reliable drug-lab testing.

Our law firm has a reputation for turning-the-tables on assault charges. Assault cases often rely on he-said-she-said statements. We have the resources, knowledge and skills to dig deep in uncovering the truth about the State’s witnesses, such as: witness motives; victim interest,  previous civil or criminal allegations; prior criminal convictions; previous divorce or CPS inquiries, child support payment delinquencies, self-defense, etc. Information obtained from our lawyers independent and thorough investigation will provide essential assault defense tools.

Legal Definition of Unlawful Drug Possession

The State must prove you knew of the drug’s existence and exercised control over the drug.  Insufficient proof of any elements above and your Houston criminal defense attorney will fight to dismiss all drug charges.

Sex crimes are serious criminal accusations. If you are being investigated for a sex offense you need to contact a qualified criminal lawyer who can assist you in preparing an airtight defense. Once retained, our lawyers will begin working for and investigating your case immediately.

Defeat the Sex Crime at the Grand Jury

Our criminal lawyers know how to defeat sex crime charges at the grand jury level. Every felony complaint must be indicted. A grand jury indicts a complaint by issuing a true-bill.  However, a grand jury may also issue a no-bill.  If a no-bill is issued the criminal accusations are dismissed and the sex crime charge can be expunged. We understand what needs to be prepared and submitted to the grand jury to achieve a no-bill. We have a criminal defense lawyer in Houston ready to speak with you know. Contact us now!

The Adamo & Adamo Law Firm has been retained on federal cases nationwide.

  2. You are contacted by an agent or U.S. Attorney.
  3. You receive a criminal target letter.
  4. You receive a criminal subpoena to appear in front of a federal grand jury.
