HONOLULU (KHNL)--She wrote stories with happy endings.
But a wrong way, head-on crash on the H-1 Freeway created a tragedy for a beloved Hawaii author, and playwright.
Monday the Honolulu Medical Examiner confirmed alcohol was in Lisa Matsumoto's system when she crashed her car last Friday.
The award-winning playwright was driving in the wrong direction on the freeway.
Lisa Matsumoto's death is still a great shock to her family and many friends.
Now, they're also dealing with this latest revelation from the Medical Examiner's office.
Police say, Matsumoto was driving in the Diamond Head direction in the Ewa bound lanes, when her car slammed head-on into another vehicle.
The 43-year-old later died at the Queen's Medical Center.
An autopsy conducted Monday found she died from injuries to her neck, and that acute alcohol intoxication was another significant factor.
The 35-year-old woman driving the other car suffered serious head and leg injuries.
Monday night Matsumoto's business partner and friend Roslyn Catracchia shared a few statements from the Matsumoto family:
"We know in our hearts that our Lisa would never have wanted this to happen. We love Lisa and will miss her deeply...we are saddenned and deeply concerned about the other people and their families who have also been affected by this tragedy.
Catraccia refused to answer any questions from the media, including one about Lisa Matsumoto having a drinking probem.
