A woman was charged with intentionally giving a dangerous weapon to a person under the age of 18 causing death after a 15-year-old girl was killed when she accidentally shot herself in the head with a handgun on June 13.

According to a probable cause statement, a witness was in a tan colored Pontiac Bonneville being driven by her boyfriend, with 18-year-old Sarae A. Barr and 15-year-old victim Amariah C. Kimbrew of Cottage Grove that Wednesday night. The witness was seated in the front passenger seat, Barr was seated in the rear passenger seat and Kimbrew was seated in the rear driver's seat, according to a criminal complaint.

The witness told police that the group was driving around Madison and needed to get gas, so they stopped at the Kwik Trip at 4402 E. Buckeye Rd. The boyfriend of the witness went in to pay for gas, while the others remained in the vehicle, according to a criminal complaint.

The witness noticed Kimbrew take a silver handgun with a black grip from a backpack that belonged to Barr. The witness then told police that no argument took place and that Kimbrew started doing "Snapchat sh—" with the gun, which means she was messing around with the weapon and her phone.

The boyfriend finished pumping gas and entered the vehicle. The boyfriend went to start the vehicle, and right as he did, the witness heard a loud bang. The witness initially thought something was wrong with her car, then heard Barr scream "she shot herself," according to a criminal complaint.

The witness, her boyfriend and Barr all got out of the car. The witness told police she was"freaking out" and heard Barr say "that bi— just went off." The witness went to bang on the window of Kwik Trip, telling the clerk to call the police.

Barr grabbed the gun and ran away around the corner and then came back. The witness, her boyfriend and Barr then all went into Kwik Trip. Barr left the store, got into the car and grabbed the gun. Barr then ran around the west side of the Kwik Trip and was gone for a few seconds, according to a criminal complaint.

Barr then returned to the store with nothing in her hands. She stayed in the store for a few moments until she took off running out of Kwik Trip toward Stoughton Road.

The witness told police Barr had the gun when she and her boyfriend initially picked Barr up. She did not know why Barr had the gun.

A 9mm Taurus handgun was recovered from a dumpster near the fence on the north side of the Kwik Trip property, according to a criminal complaint.

Barr was charged July 26 with intentionally giving a dangerous weapon to a person under the age of 18, causing death.

The identities of the witness and driver of the vehicle have not been released.
