The Honolulu Police Department says McKinney was not wearing a helmet when his scooter crashed into a wooden light pole, the Los Angeles Times reported Wednesday.

McKinney, 47, made national news in 2000 when the district attorney in Orange County, Calif. obtained his release from prison saying he had been wrongly convicted of a 1980 robbery and murder at a Burger King restaurant.

At the time of his arrest, McKinney was a member of a Los Angeles street gang.

After his release from prison, McKinney made a fortune in an ATM business with the $1 million settlement he received from the Orange Police Department.

"Understanding what you truly lost, it makes you embrace what you have," McKinney said during a 2002 interview. "I'm who I am today because of those 20 years (in prison)."
