A 37-year-old man involved in a two-car collision yesterday on 'A'ala Street died of a heart attack, according to autopsy findings.

The Honolulu medical examiner's office listed cause of death for Kevin Neeson as "cardiac arrhythmia due to dilated cardiomyopathy" and manner as natural. Neeson died at The Queen's Medical Center at 8:51 a.m., 54 minutes after the accident on 'A'ala Street south of North School Street in Liliha was reported to police.

Neeson's 2003 Chevrolet sedan rear-ended a 2002 Hyundai sedan before drifting across the roadway and hitting a parking meter and tree, police said.

The autopsy findings means the death will not be classified as a traffic fatality. Police will revise the fatality count when paperwork from the ME's office is received.
