RICHLAND — As the Washington State Patrol continues to investigate a weekend accident that left three families in mourning, the family of the driver who was going the wrong way on the foggy highway say complications from diabetes might have been a factor.
Marco De La Mora, 26, of Pasco, recently had unexplained fluctuations in his blood sugar level, said his brother, Ramiro.
Marco De La Mora had left work at Hollister clothing store at Kennewick's Columbia Center mall about 7:30 p.m. Sunday because he wasn't feeling well, his brother said.
He was killed when his eastbound pickup hit a car traveling west in the westbound lanes of Interstate 82 near the Dallas Road exit about an hour later.

Heather Davidson, 27, of Richland, and her fianc, Stephen Metzger, 30, of Kennewick, were killed in the collision, which ended up involving five vehicles.
The state patrol investigators say De La Mora might have been traveling the wrong way on I-82 in the dense fog for just a short distance because only one caller reported a wrong way driver before the collision. But that's still not clear, and officers are still waiting for a toxicology report as part of their investigation.
Ramiro De La Mora said his family is sorry for the loss to the other families in the accident. "It's a tragic, tragic day for three families, and we don't wish for anybody to suffer," he said.
Davidson, a medical assistant, was driving a Mazda that was hit by De La Mora's truck. Her boyfriend Metzger, a former Marine, was her passenger. After the initial crash, Davidson's car then was hit by three other vehicles.
The couple's 3-year-old son, Brennen, survived. He was strapped into a car seat in the back seat.
Mark Davidson, Heather's father, told the Herald on Wednesday that Brennen was doing fine at Spokane's Sacred Heart Medical Center and the family was waiting for the doctor to approve his release.
A memorial service for Davidson and Metzger is set for 3 p.m. Saturday at Mueller's Tri-Cities Funeral Home in Kennewick.
The family is accepting donations for Brennen at an account with Community First Bank in Kennewick. Mark Davidson said donations also can be made to Sacred Heart Medical Center, where Brennen is being treated.
Marco De La Mora's service is at 5 p.m. today at Mueller's Greenlee Funeral Home in Pasco, with a rosary at 6 p.m. A Mass will be held at 1 p.m. Friday at St. Patrick's Catholic Church in Pasco.
An account to help De La Mora's family pay for the funeral service has been set up at Hapo Community Credit Union under his name.
Ramiro De La Mora described his brother, who also went by Tony, as "the joy of the household."
He said the family's last contact with him was when his sister called him on his cell phone at about 8 p.m. Sunday. He said Marco picked up the call but didn't respond to her questions and she thought he must still be working and unable to talk.
The family isn't sure why De La Mora was on I-82. He lives with his family in Pasco and that's not a route home, his brother said.
Marco De La Mora, who been a diabetic since age 13, recently had been having problems with his blood sugar including at least one recent incident when it plunged dangerously low, his brother said.
Family and friends have come to the De La Mora home since the accident to share hugs and tears.
Ramiro De La Mora said his brother, a Pasco High School graduate, was well known. Ramiro said he had already had more than 100 messages about his brother on his Facebook page from people in the community.
Marco De La Mora was born in Mexico, but had become a U.S. citizen and lived in the Tri-Cities for 25 years. He was planning to attend Pasco's Columbia Basin College to start a career as an electrician.
Ramiro De La Mora said his brother, who was single, had been working hard so he could support his daughter, Marissa, age 5, and go to school.
