A man charged with killing a Maine teenager 36 years ago in a cold case that vexed authorities for years has pleaded not guilty to murder.

Police arrested 55-year-old Philip Scott Fournier in March in the slaying of 16-year-old Joyce McLain, of East Millinocket. She disappeared while out jogging.

WABI-TV (http://bit.ly/28NlpZc ) reports a bail hearing followed Fournier's plea Tuesday. Before being arrested, he was interviewed 26 times since 1980.

Fournier was identified as a person of interest in Joyce's death when he was sentenced in 2009 to 6½ years in prison for possession of child pornography.

Prosecutors say Fournier changed his story many times over the years. His lawyer has said there's a lack of physical evidence.
