COLUMBIA, S.C. (AP) - Authorities say a man serving 50 years in prison for killing his ex-wife's father has been convicted of trying to send her a bomb through the mail while behind bars by using a contraband cellphone.
Federal prosecutors said 32-year-old Michael Young Jr. was convicted in a trial this week. He was charged with transport of an explosive with the intent to kill, conspiracy and other charges.
Authorities say Young wanted to keep his ex-wife from testifying in any potential new trial for killing 49-year-old Robert Bell in the parking lot of a the Columbiana Mall in 2007.
Police have charged Michael Young, Jr. with murder in connection to Robert Bell's death. Authorities say Young is the estranged husband of Bell's daughter, Shaunna Bell. Officers say Young had been stalking Bell's daughter for weeks and confronted her at the mall, leading up to the shooting.
Prosecutors say Young also ran a drug ring on his cellphone behind bars.
Young will be sentenced at a later date.
