A 22-year-old moped rider died Tuesday after crashing into another moped on Dole Street.
The Medical Examiner's Office has identified the victim as Lee How, of Honolulu.
The crash happened about 1:45 p.m. near Holmes Hall at the University of Hawaii at Manoa.
"First moped stopped for a female pedestrian in the crosswalk. The second moped following after him did not stop and rear ended the first moped. He went over the handle bars and collided head first into the roadway, said LT. Carlene Lau, with HPD's traffic division.
"We all came out of the classroom and just overlooked the railing and what we saw was...a guy being carried into the ambulance," said Kristen Wong, who is a senior at the university.
Paramedics said the moped rider was not wearing a helmet and suffered apparent head trauma. He was taken to an area hospital, where he later died.
"Right now I'm still in shock, now that I'm actually talking about it. I never really witnessed something like this before. It kinda hits close to home because it's someone here. We don't even know who he is yet, but it's someone who is a part of our community. So it's a little uneasy," Wong said.
Police shut down Dole Street for hours to investigate.
One of his closest friends say the world has lost a wonderful person.
"He would just make you laugh like crazy, and a typical goof ball...it's funny that God has taken away one of my closest friends and it's sad to see him go...and it's hard...it's heartbreaking to be honest," said Stacey Kaneshiro.
State law mandates moped riders under 18 years old to wear helmets. Still, many riders ignore it. Lawmakers have tried to expand the helmet rule to anyone on a moped regardless of age, but it has failed.
Police and school officials could not confirm if the victim is a University of Hawaii student.
Police say speed appears to be a factor in the accident, alcohol does not.
This is the 44th traffic fatality this year, compared to 39 this same time last year.
