Arrest warrant issued for victim's son in Castle Rock fire

The whereabouts of Matthew Buchanan, now a suspect in the death of his mother, are unknown, police said.

CASTLE ROCK, Colo. — The Castle Rock Police Department (CRPD) said Friday it has issued an arrest warrant for a man in connection with the death of his mother in a fire in Castle Rock earlier this week.

Matthew Buchanan, 32, was previously named a "person of interest" in the investigation into the house fire and death of Elizabeth Bjorlow, 59.

Bjorlow died Tuesday after a fire was reported at her home on Dove Valley Place. Another person was taken to the hospital but was expected to survive. No other homes were damaged.

Buchanan is diagnosed as "severely bipolar," according to an application for a restraining order that Bjorlow filed last July.

His whereabouts aren't known, and he might be traveling outside Colorado, according to Castle Rock Police.

“This incident has shaken our community,” said Police Chief Jack Cauley in a statement. “Our main focus is locating the suspect. We are working with multiple agencies across the region and following up on every possible lead.”

Anyone with information on Buchanan can contact the Castle Rock Police Department dispatch center at 303-663-6100.
