A 22-year-old Decatur woman has been sentenced to three and a half years in prison for accidentally shooting a man to death when a stray bullet fired from her back yard struck him in his nearby apartment.

Mattisha Houston apologized to Joseph Wells' family before she was sentenced Monday for killing him in July. Houston pleaded guilty to manslaughter last month. Houston has two young children.

Wells was watching television in his apartment when the bullet flew through a window and struck him in the head.

Authorities say Houston fired her husband's gun at a tree in their back yard during a night of drinking.

The husband, Quincy Houston, has pleaded not guilty to involuntary manslaughter and is awaiting trial.
