The only survivor of the 2020 Wisconsin shootings by teenager Kyle Rittenhouse has a lengthy criminal record that includes burglary, drunk driving and a domestic incident, according to a new report.

Gaige Grosskreutz, 28, was in court just six days before Rittenhouse’s murder trial — where he was a star witness — to have a recent drunk driving charge dismissed “on a technicality,” the Daily Mail reported Monday.

Yet Grosskreutz’s list of prior scrapes with the law was not revealed to the jury when he testified at Rittenhouse’s murder trial that he attended demonstrations in Kenosha on Aug. 25, 2020, to serve as a paramedic.

But records reviewed by the Mail show that Grosskreutz has a criminal record dating back more than 10 years, the outlet said.

On Aug. 16, 2020, just days before the Rittenhouse shootings, he was arrested by cops in West Allis for allegedly “prowling” when he was nabbed videotaping police vehicles in a police department parking lot around 1 a.m.

“Gaige appeared to be videotaping personal vehicles in the rear police parking lot,” according to a police report obtained by the Mail. “Gaige made clear his anti-law enforcement views. Gaige was arrested for prowling, booked, cited and released.”

On May 9, 2015, Grosskreutz was stopped by police in Greenfield, about 40 miles from Kenosha, after cops reported he had “bloodshot and glassy” eyes — with the officers recovering a 9mm Glock 19 handgun from his vehicle.

In 2013, he was charged with smashing the bedroom window at an ex-girlfriend’s home at 4 a.m., with the woman claiming he had been harassing her on the phone.

One year earlier, was hit with a felony burglary charge in New Berlin when cops said he was caught trying to sell three stolen PlayStation consoles, the outlet reported.

And in 2010, Grosskreutz was arrested and charged with hitting his grandmother in the face during a dispute, during which he also threw a lamp and damaged a wall.

The then-17-year-old swung “a lamp into the living room wall, damaging the lamp and the wall and struck her across the face with an open hand,” a report in that case said.

Police said he was charged with disorderly conduct and criminal damage.

In addition, he has prior juvenile arrests that are sealed, the Mail said.

Rittenhouse, 18, is on trial for murder and other charges for wounding Grosskreutz and killing two other protesters in Kenosha during violent demonstrations stemming from Jacob Blake’s police shooting.

The teen has claimed self-defense.
