The shooting happened around 4:23 a.m. during a surprise party on 119th Road in St. Albans Sunday.
Police say 26-year-old Avalisa Morris was shot in the head and stomach.
Morris apparently forced two people to leave after they began to fight. She was then shot through a door she was guarding to keep the party crashers out.
Authorities say 23-year-old O'Neil Mairs is facing several charges, including murder.
