Sheriff's office: Man set fire to mother's Clackamas home

CLACKAMAS, Ore. - Clackamas County sheriff's deputies arrested a man who they said set fire to his mother's home while she was out of town Friday afternoon.

Kenneth Wayne Mroczek, 47, faces burglary and arson charges.

Firefighters responded to a house fire at 16205 SE McKinley Avenue. When fire crews arrived, they saw a man run past them and into a house next door, a Clackamas Fire spokesman said. Firefighters called sheriff's deputies to the scene to investigate.

Sgt. Dan Kraus said deputies found the back door of the neighbor's house kicked in. They used a thermal imaging device to see the man, later identified as Mroczek, was hiding in the attic.

Deputies called a SWAT team to the scene to take Mroczek into custody.

Firefighters said no one was inside the burning house. Deputies learned the house belonged to Mroczek's mother, who was out of town. Mroczek was supposed to be feeding his mother's cat while she was away, Kraus said.

Investigators believe Mroczek intentionally started the fire. His motive is unclear.

Mroczek was taken to the Clackamas County Jail. His bail was set at $300,000.

The home, valued at $120,000, was a total loss.

Anyone who spoke to Mroczek in the last 24 hours or has information about the case is asked to call the Clackamas County Sheriff's Office tip line at 503-723-4949.
