KALISPELL — Two young children are among the four people who died in what's believed to be a murders-suicide in Kalispell on Sunday, May 11, 2025.
The Kalispell Police Department responded to a mental health call at 127 Werner Peak Trail at 5:52 a.m. after Nicholas Olson-Hartley "made multiple concerning statements" to 911 dispatchers before hanging up.
WATCH:
Police responded and were unable to make contact with anyone in the home.
According to a news release, officers saw evidence that caused them to force entry into the home.
Once inside, they discovered Nicholas Olson-Hartley, 33 years old, and his wife Katie Olson-Hartley, 27, dead from apparent gunshot wounds.
The bodies of two children, 6 years old and 7 months old, were also found dead from gunshot wounds.
An initial investigation shows Nicholas Olson-Hartley killed his family before calling 911, and then took his own life.
"The Kalispell Police Department mourns with the family that is suffering from this senseless tragedy," a news release states.
A GoFundMe has been created to help Katie's family; it states:
