Police say a 30-year-old man stabbed his wife, his two young sons and his father-in-law at a home in Cheyenne, then fled in a car and is believed to have been killed in a collision on a Colorado interstate.
The Cheyenne Police Department says in a statement that police went to the home late Friday after receiving several hang-up 911 calls.
Officers found four people, including a four-year-old and a six-year-old, with multiple stab wounds from a knife. The victims were taken to a hospital and are in stable condition.
Police say officers were told that Randall Van Woerkom had attacked his family after he was confronted by allegations of infidelity.
Authorities believe Van Woerkom was driving southbound on I-25 when he crossed over the median and crashed into a field. The driver then got out of the vehicle and for an unknown reason went back onto the highway where he was hit several times by multiple vehicles, according to CSP spokeswoman Alisha Danko.
