The Iowa State Patrol has released the names of the victims involved in a fatal crash Monday morning in western Iowa’s Harrison County.

Officials say the driver of a 2000 GMC Sonoma pickup, 18-year-old Salvador Valdovinos, of South Sioux City, Nebraska, and a passenger in a 2012 Kenworth semi, 59-year-old William Griffin, of Pine Bluff, Aarkansas, died at the scene of the crash near Mondamin.

The driver of the semi, 58-year old Rebecca Griffin, also of Pine Bluff, was injured and transported by helicopter to Creighton University Hospital in Omaha. Authorities say the pickup was traveling south on Interstate 29 at around 6:50 a.m. when it went out of control and crossed the median before striking the northbound semi which was carrying dynamite.

Officials say there was no danger of the dynamite exploding.
