What Crimes Have the Longest Sentences in Milwaukee?

 Posted on July 15, 2026 in Criminal Defense

Being charged with a serious felony in Wisconsin changes your life overnight. While every criminal charge should be taken seriously, some offenses carry penalties that can keep someone in prison for decades or even for the rest of their life. 

Wisconsin uses a felony classification system that assigns different maximum penalties based on the crime involved. If they believe the circumstances warrant it, prosecutors may also seek sentence enhancements that increase penalties even further.

If you are facing serious criminal charges in 2026, you need an experienced Milwaukee, WI criminal defense attorney right away. At Gimbel, Reilly, Guerin & Brown, LLP, we represent clients accused of Wisconsin's most serious criminal offenses.

What Crimes Carry the Longest Prison Sentences in Wisconsin?

Wisconsin classifies felonies from Class A through Class I under Wis. Stat. § 939.50. Class A felonies carry the harshest penalties, while Class I felonies carry the least severe felony penalties.

The longest prison sentences are generally reserved for violent offenses involving death or serious bodily harm.

First-Degree Intentional Homicide

First-degree intentional homicide is Wisconsin's most serious criminal offense. Under Wis. Stat. § 940.01, a conviction carries a mandatory sentence of life imprisonment.

Unlike many other states, Wisconsin does not have the death penalty. Instead, life imprisonment is the maximum criminal sentence. Depending on the circumstances, a judge may allow the possibility of extended supervision after a specified period, or may order life imprisonment without eligibility for release.

Because the penalties are so severe, these cases often involve extensive investigation, forensic evidence, expert witnesses, and complex legal issues. This all takes a serious criminal defense team with experience and resources. 

First-Degree Reckless Homicide

Not every homicide requires proof that someone intended to kill another person. For example, certain fatal car accidents from driving while intoxicated can result in first-degree reckless homicide. 

Under Wis. Stat. § 940.02, first-degree reckless homicide involves conduct showing utter disregard for human life. Although it is generally classified as a Class B felony rather than a Class A felony, it can still result in up to 60 years of imprisonment.

Sexual Assault of a Child

Certain child sexual assault offenses also carry extremely lengthy prison sentences. For example, repeated sexual assault of the same child under Wis. Stat. § 948.025 is punishable by varying levels of felony charges. If the child is under 13 years old and the sexual assault causes great bodily harm, the penalty is a Class A felony. 

Other offenses involving children carry very long penalties depending on the child's age, the number of alleged victims, and whether force or great bodily harm is involved.

Armed Robbery and Other Violent Felonies

While offenses like armed robbery do not carry life sentences by themselves, they still expose defendants to decades in prison.

Examples include:

• Armed robbery

• Kidnapping

• First-degree sexual assault

• Armed burglary

• Aggravated battery causing great bodily harm

The exact sentence depends on the felony classification, the facts of the case, and any applicable sentence enhancements.

Can Sentence Enhancements Increase Prison Time?

Even if the underlying offense has a specific maximum sentence, Wisconsin law allows prosecutors to seek additional penalties under certain circumstances.

Common sentence enhancements include:

Use of a Dangerous Weapon

Under Wis. Stat. § 939.63, using, threatening to use, or possessing a dangerous weapon during the commission of certain crimes can substantially increase the maximum sentence. For example, in the case of a felony crime, the maximum term can be increased by an extra five years. 

Habitual Criminality

Wisconsin's habitual criminality statute, Wis. Stat. § 939.62, allows longer sentences for defendants with certain prior criminal convictions. Depending on the defendant's criminal history and the current offense, the maximum available sentence may increase significantly.

Crimes Against Certain Victims

Some offenses receive enhanced penalties because of the victim involved, such as crimes committed against children, public servants, and vulnerable adults. Because enhancements can dramatically increase potential prison exposure, they often become a major focus during plea negotiations and trial preparation.

Does Every Serious Charge Result in the Maximum Sentence?

Many people assume that being charged with a serious felony automatically means they will receive the maximum prison sentence. Fortunately, that is not how Wisconsin's criminal justice system works.

Judges consider numerous factors during sentencing, including:

• The seriousness of the offense

• The defendant's prior criminal record

• Whether anyone was injured

• The defendant's age and personal history

• Acceptance of responsibility

• Risk to the community

• Rehabilitation prospects

Even in very serious felony cases, experienced defense attorneys work to present mitigating evidence that may allow a lesser sentence even with a conviction. 

Can Serious Felony Charges Be Reduced?

As a criminal case develops, prosecutors may discover weaknesses involving:

• Witness credibility

• Police procedures

• Search and seizure issues

• DNA evidence

• Surveillance footage

• Cell phone evidence

• Statements made during police interviews

Sometimes these issues lead prosecutors to dismiss certain charges or negotiate reductions to less serious offenses. In other cases, evidence may be excluded because police violated the defendant's constitutional rights during the investigation.

The earlier an attorney becomes involved, the greater the opportunity to identify these issues before the case progresses.

What Happens After Someone Is Charged With a Serious Felony?

While every case is different, most serious felony cases follow a similar path. After an arrest, the defendant typically makes an initial court appearance where issues such as bail and release conditions are addressed. The prosecution then continues gathering evidence while the defense begins its own investigation.

Over the following months, there are hearings involving discovery, motions to suppress evidence, expert witnesses, and plea negotiations. Some cases resolve through negotiated agreements, while others go to jury trial.

Serious felony cases can take a long time to resolve because of the amount of evidence involved. Some take over a year. During that time, every strategic decision can affect the final outcome.
