BANGOR — The ex-girlfriend of a Maine man accused of using Facebook to lure a teenager to her death says he confessed he committed the killing.

Twenty-one-year-old Kyle Dube, of Orono, is accused of using a phony Facebook account to kidnap 15-year-old Nichole Cable, of Glenburn, and kill her in May 2013.

WZON-AM reports that Dube’s ex-girlfriend Sarah Mersinger testified Monday that he told her he killed Nichole. Mersinger says Dube covered up Nichole’s body with leaves and sticks.

Prosecutors say DNA evidence ties Dube to Nichole’s disappearance. His attorneys say someone else killed the high school sophomore. Detectives, friends and family members testified during the trial’s first week.

The trial began Feb. 23 and will last a few more days.

Dube denies killing Cable.
