Skagit County Undersheriff Tom Molitor says the body of the victim was found yesterday at his residence in the 4800 block of Blank Road in Sedro-Woolley.
The 52-year-old man appeared to have suffered wounds to his head from a chainsaw.
A tenant on the property was taken into custody this morning for the murder.
Police believe a dispute between the suspect and the victim lead to the assault.
The investigation continues.
