Person of interest in Silverton Rd. house fire arrested

SALEM, Ore. -- A man has been arrested on suspicion of a series of crimes and is a person of interest in a house fire in a bizarre case that investigators are still piecing together.

William A. Riley Jr., 41, was arrested after he crashed a car into a street sign in the 7200 block of Silverton Road near Salem, police said.

Investigators then said they linked Riley to several trespassing incidents and thefts in the area that took place in the early morning hours.

He's also a person of interest in the suspicious fire that badly damaged a home in the 7200 block of Silverton Road.

It took firefighters almost an hour to put out the two-alarm fire on Monday morning. The fire affected both the two-story farm house and an unattached garage.

When firefighters arrived, they found no residents. The family was out of town on vacation.

Investigators said Riley does not know the residents and they couldn't pinpoint any connection or a motive yet.

Riley was booked in the Marion County Jail on charges of failure to perform the duties of a driver, two counts of first-degree criminal mischief, three counts of second-degree criminal trespass, second-degree criminal mischief, unlawful entry into a motor vehicle and third-degree theft.

Anyone who thinks they may have been a victim of Riley on Sunday night or Monday morning, should call Detective Nancy Hubbard at 503-316-6635.
