A 19-year-old Sapulpa woman accused of shooting her boyfriend in the head was charged Friday with first-degree manslaughter.

Tiffany Wesley was also charged with possession of a firearm while under supervision stemming from the March 11 shooting of Evan Cochran Stout Jr., 19, in a car in the 2200 block of North Boston Place in Tulsa, court records indicate. Stout died two days later after being declared brain dead.

The charges against Wesley allege that she shot Stout as an “unnecessary act” while Stout was assaulting her.
