A 19-year-old college student critically injured this week in a moped accident was to be removed from life support today, his family said.

Shirzad Soleymani sustained significant head injuries in an accident early Tuesday, when he lost control of his 1988 Yamaha moped in Waikiki and struck a tree. His family said doctors determined he was brain dead after the crash, but he was kept on life support yesterday to preserve his organs for donation.

His parents alerted The Advertiser about their son's death to publicize his final gift: Their son's organs will help at least 10 people prolong their lives. "They want to know that out of one life comes many others," said Soleymani's aunt, Mitra, of San Diego, Calif.

Shirzad Soleymani grew up in California, but came to Hawai'i recently when his father was stationed here with the Navy. His aunt said the teen was a good student and a good kid. He was going into environmental sciences at Hawai'i Pacific University, she said.

When the moped crash happened, his aunt said, Soleymani was returning home from a quick run to the store with a friend. The friend was on a motorcycle and did not get injured, the aunt said.

Honolulu traffic police said the crash on Seaside Avenue happened about 1:05 a.m., when Soleymani attempted to turn left from Kalakaua Avenue onto Seaside, lost control and hit a tree.

Soleymani was not wearing a helmet.

He was thrown from the moped.

Police said drugs and alcohol did not appear to be factors in the crash.

Soleymani is survived by his parents. He was an only child.
