Testimony went into a fourth day in Altus Monday, in the trial of a man accused of killing an Altus mother in February 2012.
Two women, who say they bought drugs from Melissa Bost, 49, testified.
Bost's body was found in her car with her dog in an Altus alley.
Manuel Daniel, 46, is charged with the first- degree murder of the mother of three.
He faces life in prison or life without parole.
In court Monday, Mindy Wedgeworth, who says she bought drugs from Bost, and was also friends with Daniel said she spoke to Daniel several times on the phone the day police found Bost dead.
Wedgeworth says Daniel called to ask her if she'd seen Bost and that she was missing.
Wedgeworth says when she found out Bost was dead, she called Daniel with the news.
Then, she says Daniel told her police were going to be coming for him, since he was the last person to see her, around midnight the night she disappeared.
She says he also told her he was cleaning house that day.
Investigators believe Daniel killed Bost in his home, and with someone's help, placed the body in her car with her dog and drove it to an alley.
Investigators believe he ripped out carpet that had her blood on it.
The defense attorney has pointed to other possible suspects, including a drug supplier to Bost, as the possible killer.
Testimony continues Tuesday morning at 9 a.m.
