A judge has sentenced a 16-year-old boy to 25 years to life in adult prison as an accomplice in the sledgehammer slayings of a prominent attorney and his wife in April 2013.

Jamall Vaughn was 14 when he walked eight miles with 18-year-old Shawn Ford from Akron to the New Franklin home of Jeffrey and Margaret Schobert, where he watched Ford beat the couple to death with a sledgehammer. The same judge gave Ford a death sentence Monday.

Vaughn pleaded guilty in February to aggravated murder and aggravated robbery charges. He was accused of inflicting superficial knife wounds on Jeffrey Schobert's back after Ford attacked him.

Vaughn's attorney on Tuesday said Vaughn had fallen under Ford's control.

Prosecutors said Ford was angry with the couple, who were his former girlfriend's parents.
