The suspect in Monday's fatal crash in West Oahu is facing charges, and police say speed and a medical condition may have been factors. Investigators have opened both negligent homicide and negligent injury cases against the suspect who is in his 60s.
The crash on Farrington Highway in Kapolei backed up afternoon traffic for hours as police closed lanes to investigate.
Paramedics say the multi-vehicle crash happened near Campbell Industrial Park at around 3:40 p.m.
Police said the driver of a minivan was driving erratically on Farrington Highway westbound when he crashed into a concrete barrier, went over a grassy median and slammed into two cars headed eastbound.
"The first vehicle he collided into, the driver, was pronounced dead at the scene. The second driver was a female driver in her 40s and she was taken to an area hospital in fair condition," said Lt. Carlene Lau, Honolulu Police Department.
The suspect went to the hospital in critical condition but has since been upgraded to fair condition.
Both eastbound lanes of the freeway were closed until about 7:30 p.m. All westbound lanes had opened hours earlier.
The closure snarled traffic for hours, and a number people on social media said the roadway was a parking lot.

Waianae High teacher Dominique Heuermann said she left school about 4:15 p.m., and hit bumper-to-bumper traffic in Nanakuli about 15 minutes later.
"People were actually turning around over the medians and then going on the sides, the safety lanes. It's been crazy," she said. "Everybody's just stuck."
She said she lives in Kapolei and it usually takes her about 30 minutes to get home.
"I've been sitting here for two hours ... so this is crazy. It's really insane," she said.
Chris Gago was on the bus heading to his second job in Kapolei when the bus driver was instructed by police to pull over and wait at Hookipa Beach Park. Already late for work, he decided to start walking.
"We just have to sit it out or take a chance and walk, so we took a chance and walked three hours later," Gago said.
