How a Former
Prosecutor Can Help

As a former prosecutor, Gus has unique insight into how the prosecution builds a case against you. He knows how they investigate your case, the tactics they use to pressure you into accepting a plea deal, and more importantly, what shortcuts they take. This allows him to effectively challenge every aspect of the prosecution’s case against you.

Gus prides himself on an aggressive pre-investigation process designed to minimize the charges or get them dismissed all together. Instead of giving the prosecution time to build a case against you, Gus starts working on your case from the moment you hire him by reviewing the evidence, reaching out to the detectives investigating your case, and using his own team of investigators to challenge any evidence collected by the prosecution.

Experienced Trial Lawyers

If your case must go to trial, then you need a criminal lawyer with a proven track record of taking cases to trial and winning. Both as a former prosecutor and criminal attorney, Gus has established himself as a successful courtroom litigator who can take a case before a jury and win. His courtroom skills serve you well in and out of the courtroom, as the prosecution is more likely to offer a favorable plea agreement if they know that you’re represented by an experienced litigator. Don’t face criminal charges on your own, find out how we can assist you so you can get back to your life and avoid a criminal record.

When facing criminal charges, the quality of your legal representation can greatly impact the outcome of your case. The top rated defense lawyers at Kostopoulos Law Group will use their unparalleled experience to help you achieve the NOT GUILTY verdict you deserve.

Protect Your
Rights

After an arrest, the most important thing you can do is to hire an attorney to protect your legal rights. Remember, you are innocent until proven guilty. By protecting your rights, such as your right to remain silent and right to have an attorney present, an experienced criminal lawyer forces the prosecution to prove their case against you, instead of allowing the police and prosecution to build a case against you based on your statements.

Additionally, Gus’s extensive prosecutorial experience means he knows what type of evidence the prosecution will rely on and the experts they will use against you. You can rest assured that Gus will aggressively attack any so-called “expert” opinions the prosecution attempts to use against you.

Frequently asked
questions

If you are under investigation, it is not in your best interest to speak with the police. During an investigation, you may be contacted by a detective who will say, “we just want to get your side of the story.” That’s false. They are solely attempting to acquire evidence that can be used against you at a later time. They may also say, “don’t you want to clear your name?” Again, under no circumstance should you speak with the police. If you believe there is a pending investigation against you, then immediately contact a criminal lawyer.

No. You are not legally required to consent to a search. Although exceptions exist, police are generally required to have a search warrant if they want to search your house. While police may have more leeway regarding the search of your vehicle, you should never consent to a search of your home, car, or person.

The most important thing you can do during an after the arrest is REMAIN SILENT at ALL TIMES. Do not speak with anyone about your case except your attorney. That includes police, other inmates, or over the phone while in jail. If arrested, exercise your right to remain silent and inform the arresting officers that you want an attorney.

If a police officer attempts to speak with you after your arrest, politely inform them that you want an attorney. Remember, police can continue interviewing you if you’ve only exercised your right to remain silent. However, they must immediately cease their questioning if you tell them you want a lawyer present.

When a person is arrested, they must either sit in jail to await trial or the judge may set a bond. If a person is on bond, he or she must follow all of the judge’s bond conditions such as to not leave the state without Court permission, not commit other crimes, and not contact witnesses. Often the person must report to the Pre-Trial Services division of Probation and submit to random drug tests and other conditions. A person on bond must often make a cash deposit in order to be released. If the person violates the bond conditions, the bond may be revoked. If you’ve been arrested and need further advice, call today.
