Crystal Mountain took the stand Monday, and said that Lisa Holland told her that "she killed him with a hammer."
Mountain is in jail for solicitation. She says she and Lisa became friendly because she was kind to Lisa when other inmates were not.
She says after about a week, Lisa opened up. She says she said, "Tim was a stupid man and it was his fault we're in jail." She says she described hitting Ricky on the head with a hammer in the hallway in their home, wrapping him in trash bags, and then cleaning up the murder scene while Tim dumped the body somewhere.
Defense attorneys pointed out Mountain had a short-term memory problem from a previous accident and bipolar disorder. She admitted on the stand she took documents from Lisa's jail cell, but says she never read them and returned them immediately.
Mountain was not offered a deal for her testimony.
The court also heard from Peggy Cox, Ricky's first grade teacher at Cascades Elementary School. She talked about her concerns of abuse, though admitted she didn't have any specific enough to report at the time Ricky was her student.
