David Lee Rickerson, 40, faces a charge of capital murder in the slaying of Edward Sebastian. He admitted to officers that he was involved in the elderly man's death, police said.

Officers were called to the 8900 block of Craige Drive, near North Prairie Creek Road, about 1:30 p.m. Saturday for a welfare check and found Sebastian's body.

About two hours earlier, Rickerson was involved in a crash in the 800 block of Mt. Auburn Avenue in Old East Dallas. He told the officers who responded that he had stolen the truck he crashed, a black Toyota Tundra that belonged to Sebastian, according to the arrest warrant affidavit.

The day Sebastian's body was found, a witness told officers that Rickerson had been driving the dead man's truck for three days. The witness said that Rickerson admitted to killing Sebastian, asked for help moving the body and gave him a check in Sebastian's name, the affidavit said.

The witness turned the check over to police. He also said that over a couple of days he and Rickerson took lawn equipment from Sebastian's house and sold it to pawn shops and lawn crews in the area, the affidavit said.

Rickerson was arrested about 11:15 a.m. Monday in the 3100 block of Lagow Street in South Dallas and booked into the Dallas County Jail. Bail has not yet been set.
