Witnesses interviewed by The Times said Shanahan was subsequently beaten by police officers after he kicked over a plastic crowd barricade.
According to the police report, however, this is what happened after the concert ended:
An officer on patrol saw Shanahan standing with his body rigid and a blank stare on his face. The youth didn't respond to questions, the report says, and he suddenly dropped to his knees and started yelling and laughing.
When he resisted the officer's effort to handcuff him, two more officers were called to assist. Shanahan started kicking and "trying to bite any part of an officer that was near his mouth," the report states.
After Shanahan was wrestled to the ground, he broke free from the officers and started to stand. Then one officer, according to the report, "placed him in a carotid control hold."
The report says Shanahan continued to struggle as three officers got on top of him and others bound his legs with restraints. Eventually he stopped struggling but continued yelling, the report says. Officers put the youth in the back seat of a patrol car and headed for the Inglewood police station--until they noticed that Shanahan had stopped breathing.
They changed course and took him to nearby Daniel Freeman Memorial Hospital, where Shanahan was pronounced dead.
