Sex crimes are among the most serious criminal matters in Dupage County. Simply being accused of a sexually-based crime can be devastating. You’ll be subject to harsh social stigmas and your reputation will be ruined. If you’re convicted, you can spend serious time behind bars. You’ll have a criminal record and may even be required to register as a sex offender. Have you been accused of a sex crime in Dupage County? You need to speak with an experienced criminal defense attorney today.

Our attorneys have successfully defended clients against charges for a variety of sex crimes, including:

You can only be convicted of a sex crime if the state can prove that you are guilty beyond a reasonable doubt. This can be difficult if the state lacks physical evidence to support its case against you. Many sex crime cases rely heavily on circumstantial evidence and witness (or victim) testimony.

Our attorneys will fight to prove that the state’s evidence is insufficient to support a finding of guilt. Undermining that state’s case can be very effective in defeating criminal charges. Without solid evidence, the state may be forced to offer a plea or drop the charges.

It is illegal to possess, purchase, sell, or manufacture controlled substances within the state of Illinois. In Dupage County, police have made it a priority to investigate and charge drug crimes. Under the Illinois Controlled Substances Act, drug crimes can carry incredibly harsh criminal penalties. Some even require mandatory imprisonment and expensive fines. Relatively minor infractions involving marijuana may be classified as misdemeanors. However, most drug crimes in Chicago will be charged at the felony level.

When you are arrested for a drug crime in Chicago you must remain silent. The only thing you should say to police is that you want to speak with an attorney. Our lawyers have successfully handled some of the most complex drug crime cases in Chicago. We have defended clients against a variety of charges, including:

Just because you’ve been accused of a drug crime in Dupage County doesn’t mean that you’ll be convicted. Our attorneys will aggressively defend you against any drug charges that you may face. We will investigate your alleged crime and determine if the state obtained evidence in violation of your rights. With this information, we will determine where we can attack the state’s case against you. If the state cannot prove that you are guilty of all elements of a drug crime you cannot be convicted.

Theft occurs when you take property that belongs to someone else without permission. In Illinois, 720 ILCS 5/16 broadly defines theft to include larceny, fraud, and embezzlement. The common theme of these crimes is taking property without permission. You can face charges for an act of theft if you take property with the intent to keep it from its owner. How serious are theft crimes in Chicago? It depends on the value of the stolen property. Petty theft, which is usually a misdemeanor, involves property valued at less than $950. Grand theft, which can be a felony, involves property valued in excess of $950.

The stakes can be different, however, if you take (or try to take) property from a store. Retail theft, as defined in 720 ILCS 5/16-25, can be a felony if the property involved is worth more than $500. Unlike other theft crimes, you don’t actually have to remove property from the store. You can be guilty of shoplifting if you intend to commit the crime.

Drinking and driving in Dupage County can have devastating consequences for you and your family. It is against state law to operate a motor vehicle while under the influence of drugs or alcohol. There are two primary ways you can be charged with DUI in violation of 625 ILCS 5/11-501. The first is if your BAC exceeds the legal limit of .08 percent. The second is if an officer believes you are intoxicated and incapable of driving safely.

A first-time DUI is typically a misdemeanor. However, it can result in up to one year in jail and the loss of your driving privileges for 6 months. You can lose your license for 3 years if you have prior convictions or refuse to cooperate with police. A DUI can also be a felony. You may be charged with felony DUI if you drive with a minor in the vehicle or hurt another person.

Evidence in Dupage County criminal DUI cases should always be challenged. The chances of conviction are slim if the state doesn’t have evidence to support its case against you. Our attorneys know how to handle complex DUI matters and get the best possible outcome in your case. Call us today to schedule a free case assessment.

Illinois is tough on crime when it comes to domestic violence. Acts of domestic violence, as defined in 750 ILCS 60, can include:

Domestic violence is a very specific category of abuse. It requires victims and defendants to share a close relationship or bond. This includes spouses, parents, children, dating partners, and roommates.

Anyone accused of domestic violence should speak with a lawyer as soon as possible. False allegations aren’t uncommon. This is often true if you are in the middle of a divorce or family dispute. Many domestic violence cases, particularly those involving false claims, lack physical evidence.

Our attorneys will highlight the fact that the state doesn’t have the proof it needs to prove its case against you. This will help you avoid the very harsh consequences of a domestic violence conviction. Contact us today to schedule a free case assessment.

There is perhaps no more serious crime than taking the life of another person. In Illinois, murder is broken down into two different crimes: first-degree murder and second-degree murder.

First-degree murder [720 ILCS 5/9-1] occurs when you intentionally and purposely kill another person. You can also face first-degree murder charges if you kill another person while committing a felony. If convicted, you’ll face a minimum of 20 years behind bars. Second-degree murder [720 ILCS 5/9-2] occurs when you kill another person in a heat of passion after being provoked. If convicted, you will face between 4 and 20 years in prison.

How can you tell the difference between degrees of homicide in Illinois? First-degree murder tends to be premeditated and thought out. Second-degree murder must be the result of an immediate provocation.

If you are facing homicide charges in Illinois you need the help of an experienced lawyer. Remember, the state must be able to prove that you are guilty of the crime beyond a reasonable doubt. A well-constructed defense can prevent the state from satisfying this high burden of proof. In certain situations, affirmative defenses can also be helpful. This strategy involves admitting to the crime, but offering a legal explanation for your actions. This can help to minimize the fallout from your arrest.
