The man and woman found dead in a car in the parking lot of a Buffalo Wild Wings restaurant in Coon Rapids last month died of carbon monoxide poisoning, with recent cocaine use a "significant condition," authorities said Tuesday.

The two have been identified as Alissa Spah, 20, of Andover, and Antonio Perfetti, 22, of Ham Lake.

Their deaths were ruled accidental by the Midwest Medical Examiner's Office. They were found about 3:30 p.m. Oct. 5 in the parking lot at 3395 River Rapids Drive NW., authorities said.
