Detroit police said Saturday that FerDarius Shine turned himself at a hospital. He is considered mentally unstable.
Shine is accused of opening fire on his family members Friday night, then fleeing the scene near Greenfield Road and Interstate 96 on Detroit's west side.
Police spent most of Friday night searching for Shine.
He was at his grandmother's house when he started talking about Satan, God and the Devil.
"Something they didn't understand and couldn't comprehend," said Dwane Blackmon, of Detroit Police Homicide.
He suddenly opened fire on his 65-year-old grandmother, his 48-year-old aunt and his own 7-year-old daughter.
Shine's own mother also was at the house. She was able to get him to stop shooting. His grandmother and aunt both died at the house.
Shine's daughter was rushed to Sinai Grace Hospital where she is in critical condition.
Sources say Shine does have a concealed pistol license. The gun was found after the shooting at the home.
His mother told police Shine is "possessed." Sources say he left the house screaming, "The Devil made me do it."
"Apparently he had been off his medication," said Blackmon. "You know, this is one of those incidents that I don't think anybody will be able to explain."
Police say around 1:30 Saturday morning, Shine checked himself into a local hospital for psychiatric evaluation.
