A Midvale man remained in the Salt Lake County jail Tuesday night after being charged in connection with 10 fires deliberately set in the southwest and south-central parts of the Salt Lake Valley.

Shawn Robinson Olsen, 22, was charged Monday in 3rd District Court with two counts of aggravated arson, a first-degree felony, eight counts of arson, a second-degree felony, and seven counts of burglary, both second- and third-degree felonies.

Most of the fires occurred at residences, some of which were vacant or under construction, according to the charges. One of the fires occurred in 2000. The majority of the fires occurred toward the end of last year or the beginning of this year.

A van also was set on fire and received about $2,000 in damage. In Bluffdale, a storage shed behind a gas station was lost in a fire. The shed and the contents inside were valued at about $10,000, the charging documents state.

The most recent fire was set April 4 near 700 East and 6800 South. That duplex is near the man's listed address, according to the charges. The duplex was vacant and under construction, firefighters said, and a second alarm was called on that blaze. Damage exceeded $200,000.

The first two fires of 2003 occurred Aug. 11 — a house near 12200 South and 1700 West sustained about $120,000 worth of damage, and a house near 10700 South and 1700 West had damages of at least $5,000, the charges state.

Investigators from a dozen local, state and federal agencies assisted the Salt Lake County District Attorney's Office, according to a statement released Monday by the DA's spokesman.

The charges do not explain how Olsen was connected to the fires.

"There's no motive listed in the probable cause statement (of the charges), so I won't comment on a motive," DA's spokesman Robert Stott said.
