DETROIT (CBS/AP) State police will take over the investigation into the death of 7-year-old Aiyana Jones who was fatally shot by a Detroit police officer Sunday during a raid at the girl's home, a prosecutor said Monday.

According to Assistant Chief Ralph Godbee, the Detroit police barged into the home with their guns drawn searching for a homicide suspect that was involved in the slaying of a 17-year-old boy. One of the officers was allegedly involved in a scuffle with a woman inside the home when the gun went off and fatally struck the sleeping child in the neck.

Chief Godbee believes the gun was not fired intentionally, but Wayne County Prosecutor Kym Worthy said bringing in the state police to investigate the killing would avoid any appearance of a conflict of interest.

"This is a tragedy of unspeakable magnitude to Aiyana's parents, family and all those who loved her," Godbee said. "It is a tragedy we also feel very deeply throughout the ranks of the Detroit Police Department."

Although police eventually found the 34-year-old slaying suspect they were looking for during the raid, it does not console Aiyana Jones' father Charles Jones who said "Aiyana was a lively child."

Charles Jones remembers covering his daughter with her favorite blanket as she slept peacefully on the couch of their Detroit home before heading to bed early Sunday. He awoke to sounds of a flash grenade followed by a gunshot, and immediately rushed to the living room where he says police forced him to lie on the ground with his face in his daughter's blood.

"I'll never be the same. That's my only daughter," Jones told WXYZ-TV.
