Prosecutors: Boy, 13, killed over about $70

DETROIT -- Three people were charged Thursday in the death of a 13-year-old Detroit boy prosecutors say was beaten and choked and whose body was dumped in a vacant lot after he picked up about $70 that had been dropped outside a convenience store.

"There's not a whole lot that shocks seasoned prosecutors, but there are some things you just cannot explain," Wayne County Prosecutor Kym Worthy said at a news conference, where she announced the charges.

Gregory Walker, 45; Lillian Roberts, 43; and Walker's son, 26-year-old Earnest Coleman, face charges of murder, unlawful imprisonment, kidnapping, torture and gun crime. Walker is accused of choking Deontae Mitchell to death with help from Roberts and Coleman. Walker and Roberts are romantically involved. Police declined to discuss any potential prior relationship between Deontae and the defendants.

All three were arraigned Thursday afternoon on the charges. They were jailed and have a hearing set for next Thursday. Coleman had been charged and arraigned on kidnapping in the case over the weekend.
