Gregory Walker, Lillian Roberts and Ernest Coleman are charged with the murder of 13 year-old Deontae Mitchell. All three are charged with kidnapping, torture and felony murder and face life behind bars if convicted. Walker, 45, the man accused of choking the 13-year-old to death is also charged with first degree premeditated murder. Deontae's body was found in a field on Detroit's east side earlier this month after he was kidnapped outside of a store.
