Watkins received more than 50 years in prison after he pleaded guilty to his role in Carruth’s efforts to kill Cherica Adams in 1999. He was the one who fired the shots that eventually killed Adams. He was sentenced for second-degree murder, conspiracy and other charges.

Adams was shot in her car as she drove away from a shopping center in December 1999. She died weeks later. Her son was born after an emergency Caesarean section.

He suffers from multiple disabilities and was raised by Adams’ mother. Watkins pleaded guilty in exchange for testimony that Carruth paid Watkins to kill Adams and her baby.

Carruth was acquitted of first-degree murder but convicted of conspiracy to commit murder and other charges. He was sentenced to between 18 and 24 years in prison and was released in 2018.

He played for the Carolina Panthers from 1997 to 1999. The Panthers selected him in the first round of the 1997 draft out of Colorado.
