He told authorities that it had upset him when 43-year-old Michael Bridges threatened to hit 36-year-old Desiree York, Later, when he found Bridges passed out in the back of the box truck in the Penobscot Plaza parking lot, he closed the back door and started a fire nearby.

He said he didn't know York was also in the truck until he heard screaming he believed to be coming from her. Police say he was the one who called 911. The State Medical Examiner determined the couple died of asphyxiation.

De St. Croix was in court yesterday, charged with arson and murder. He pleaded not guilty and is being held without bail.
