MINNEAPOLIS - Minneapolis police say a 17-year-old is being held in the fatal shootings last weekend of a baby and a young man on the city's southeast side.

The suspect was arrested and booked into the juvenile detention center early Wednesday morning. He is suspected of firing the shots that killed 7-month-old Jayden Eric Redden and 20-year-old Gustav Duane Christianson II. The two victims were found in the back seat of a vehicle Sunday by officers responding to a shots fired call at 11th Avenue South and 26th Street East.

Julia Johnson, Christianson's sister, told KARE (NBC Minneapolis) that Christianson was recently released from prison, was formerly affiliated with the Native Mob gang and was in a treatment program. On Sunday police said they believe Christianson was the intended target of the shooter.

Police say there will be no further information on the case until the Hennepin County Attorney's Office makes a decision on whether charges will be filed.
