Two men have been arrested on murder warrants following a bizarre explosion that killed a Grangeville man last weekend.
Robert Wayne Matthews, 19, of Grangeville, was arrested at the Idaho County Courthouse on Wednesday in the death of Stacy Calhoun, the sheriff’s department said.
On Tuesday night, Gary Lyn Gordon, 28, also of Grangeville, was arrested without incident by Sheriff Gene Meinen.
The sheriff’s office said the investigation continues.
Gordon was jailed on $250,000 bail Wednesday. Matthews was being held without bail.
Calhoun, 28, the father of three, was killed Saturday night when an explosive device detonated in the back of his pickup truck.
The sheriff’s office said someone threw the device into the back of Calhoun’s truck about 10 p.m. Saturday.
Calhoun and a female companion noticed a red glare they thought was perhaps a cigarette butt and Calhoun had begun throwing snow on the device when it detonated.
The explosion blew a hole through the side of the pickup and Calhoun was struck in the legs, severing a major artery. He was taken to Syringa General Hospital, then by ambulance to St. Joseph Regional Medical Center in Lewiston, where he died early Sunday morning. The woman was not hurt.
The incident is also being investigated by the federal Bureau of Alcohol, Tobacco and Firearms and the Idaho Criminal Investigation Bureau.
