Lisa M. Wilbert, 31, of Center Township is housed in Butler County Prison on $100,000 bail after police found four handguns in her backpack and suspected drugs and money in her purse during a traffic stop Tuesday night.

Four handguns — two loaded and one stolen — were seized from a woman’s backpack in a car Butler police stopped Tuesday night.

But that’s not all officers found. In her purse, police said, were more than two dozen bags of suspected heroin along with suspected crack cocaine, a scale and hundreds of dollars.

The findings landed the owner, Lisa M. Wilbert, 31, of Center Township, who also was wanted on two unrelated warrants, in the Butler County Prison on $100,000 bail.

City officers were looking for Wilbert shortly after 11 p.m. when they spotted her car leaving an apartment complex on the city’s north side.

Butler police already had an arrest warrant for the suspect and the sheriff’s office had their own bench warrant for her.

Wilbert was riding in the back seat of the car that officers pulled over in the 400 block of North Washington Street, and at first she refused to identify herself, said police Lt. John Johnson.

While at the car, officers also noticed the defendant reaching for a backpack that was on the seat next to her, police said.

She eventually gave her name and was immediately arrested on the warrants. She resisted but subsequently was placed in handcuffs and seated in back of a patrol car.
