Moore and the teen are charged with homicide, involuntary deviate sexual intercourse, burglary, robbery and other offenses in the Dec. 15 killing at Mathewson’s Lancaster home.

Moore’s lawyer didn’t immediately return a message. He’s said his client isn’t responsible for Mathewson’s death.

Mathewson taught at Brownstown Elementary school. Police say she’d been home alone before she was killed. Police say the alleged attackers didn’t know her.
