LA CRESCENTA (CBSLA) – An autopsy has determined that a University of California, Irvine student died of accidental alcohol poisoning at an off campus fraternity party back in January, authorities reported Monday.

The Orange County coroner’s office confirmed Monday that an autopsy found that 18-year-old Noah Domingo of La Crescenta had a blood-alcohol level of 0.331 when he died at about 3:30 a.m. on Jan. 12. That is more than four times the legal limit if he were to drive. No other drugs were found in his system, the coroner’s office said.
