CASPER, Wyo. (AP) -- There will be a memorial service today for the victims of a grisly murder-suicide that happened on a Wyoming campus last week.
The memorial is scheduled for 4:30 p.m. at Casper College.
On Friday, witnesses say 25-year-old Christopher Krumm barged into a computer science class and shot his father in the head with an arrow. His father taught the class.
Police say 56-year-old James Krumm fought with his son before he died. They say that gave students time to flee without getting hurt. Christopher Krumm died of self-inflicted knife wounds.
Earlier that morning, Krumm killed his father's girlfriend, 42-year-old Heidi Arnold. She was found dead of stab wounds in front of the home she shared with James Krumm.
Arnold was a math instructor at the college.
