MIAMI (AP) -- An autistic teenager who had been in a coma since a confrontation with police officers last month has died.

Kevin Colindres, 18, died Friday. He had been hospitalized since officers were called to his home after he had an outburst.

Stuart Grossman, who represents the parents in a lawsuit against the city, said Friday the officers pinned Colindres to the ground and held his ankles in the air, cutting off his breathing. The lawsuit claims the officers' actions caused the teen to stop breathing and left him comatose.

"It's obvious from the extent of his brain damage that he had been asphyxiated by the police for quite some time," Grossman said.

An autopsy was pending.

As the family had done three times before, Colindres' sister called police Dec. 12, after the teenager became combative with family members. When an officer arrived minutes later, she found Colindres calm and sitting on a couch, according to police.
