Driver in fatal Nampa overpass crash released from hospital

It may take some weeks for Idaho State Police to finish investigating the Tuesday crash, in which a Chevrolet Impala veered off of an Interstate 84 overpass and hit a pickup truck on the road below it.

That’s at least partly because investigators are waiting for toxicology results, ISP spokeswoman Teresa Baker said Friday.

John Pew, 64, of Nampa — the driver of the pickup — was taken from the crash site to Saint Alphonsus Regional Medical Center in Boise, where he later died.

Police say Tyler Callahan, 21, was the driver of the Impala. He and two juvenile passengers were also taken to Saint Alphonsus, where Callahan was initially listed in serious condition. He has since been released, Baker confirmed; conditions for the two juveniles remained unavailable because their names have not been released.

Idaho State Police arrived at the scene of the accident at 5:17 a.m. Tuesday. According to the agency, Callahan was westbound on I-84 when his Impala veered off the overpass crossing Northside Boulevard. It then struck Pew’s pickup, which was headed north on Northside.

It was not immediately clear why Callahan veered off the interstate. Northside Boulevard was closed for nearly three hours as emergency crews worked at the scene.
