“It is rare that we use the automatic waiver to charge juveniles as adults. But the alleged facts in this case are especially heinous and violent,” Prosecutor Kym Worthy said. “The evidence in this case will show that these defendants called an Uber with a plan to rob and carjack the driver, beat and bludgeoned him, and left him in an alley to die.”

It happened on Jan. 21 when police found 60-year-old Timothy Perkins of Southfield in a southwest Detroit alley. Police say Perkins had been beaten with a hammer and had multiple stab wounds to his body. He was transported to a local hospital and later died.
