IDAHO FALLS, Idaho -- Idaho Falls School District 91 says it will have counselors and crisis teams available Monday for students and staff following what police describe as a murder-suicide involving an Idaho Falls High School instructor.
Police say 49-year-old math teacher Keith Matthias on Friday evening shot and killed a man having an affair with his wife and then shot and killed himself after police forced his vehicle to a stop a short time later.
Matthias' wife, Jennifer Matthias, 41, is a sixth-grade teacher at A.H. Bush Elementary School in Idaho Falls.
The Post Register reports the couple have three children.
Police say Jack Purcell, 46, died about 8 p.m. Friday while sitting in his truck at a Wal-Mart parking lot after being shot in the head numerous times with a large-caliber revolver.
In 2003, Purcell was sentenced to 18 months in prison following convictions for grand theft and domestic violence in Kootenai County in northern Idaho.
