According to investigators, it was Bethea who fired the shot that killed Asselin.

After returning to the Tri-Cities, Combs and Bethea met with Asselin, Sarabia and the other women at 3-City Sports Bar.

The women agreed to follow Combs to the party.

Before going to the party, Asselin went back to her father's house to find out who she was with.

Bethea and her friends got into a vehicle with people they knew from the area.

According to the documents, security footage shows the vehicles Combs and Bethea were pulling in front of Asselin and driving side by side.

The investigators think this is when they started shooting. They don't know if they believe there were three people shooting or if there was only one shooting.

According to the documents, Bethea may have had a sawed-off shotgun and pistol with extended magazine, as well as the gun that Combs used.
