(AP) — A Wichita woman has been sentenced to four years and eight months in prison for firing a bullet through a wall and killing a man in the next room.

36-year-old Desiree Boone was sentenced Thursday for involuntary manslaughter. She also received a one-year sentence Thursday for threatening another man with a gun.

Boone had a long history of mental illness. She told a Sedgwick County jury in April that her handgun discharged accidentally in November 2011 as she and her cousin argued in a home they shared near Friends University. The bullet struck 47-year-old Earle Sullivan Jr. in the head and killed him instantly.

Sullivan was helping the cousin move a table and curtains into the home when he was shot.
