Minneapolis police have arrested a 17–year–old boy suspected in a double–homicide.

The suspect was booked into the Hennepin County juvenile jail on suspicion of murder.

Seven–month–old Jayden Redden and 20–year–old Gustav Christianson II were fatally shot Sunday afternoon in the back seat of a car.

Police say the shooting was a targeted attack.

Christianson was not the father of the child.

His sister said Christianson had recently been released from jail and had a past history with gangs.
