(KHNL) - There is some new and disturbing information about the tour bus driver involved in Monday's deadly crash in Kahaluu.
That same driver was involved in another collision that same day.
Three days after this horrific crash, friends of Corey Voss continue to struggle with their sudden loss.
This was the second crash of the day for the tour bus driver, who celebrated his 49th birthday the day before.
Sources say about eight hours before the Kahaluu collision, Steve Oshiro was driving his tour bus near the intersection of Beretania and Punahou Streets, when he slammed into the back of a city bus.
Roberts Hawaii, the owner of the tour bus, says in such minor incidents, no alcohol or drug testing of the driver is required.
Eight hours later, Corey Voss was dead, and Oshiro was under arrest.
Steve Oshiro has been terminated for failing to comply with company policies.
Upon learning he was released by the police, Roberts Hawaii asked Mr. Oshiro to submit to a drug and alcohol analysis as required by company policies.
Mr. Oshiro's attorney refused to allow the test.
