Fire raged through a Utah Highway Patrol trooper's home early Saturday and another home eight blocks away, causing extensive damage to the first and destroying the second.

Investigators say the fires may have been set intentionally but aren't sure whether the trooper was the target of a person who has promised to harm area law enforcement officers.The two house fires mark the latest in a spate of house, nursing home and apartment fires throughout the Salt Lake Valley since Tuesday.

The first Saturday blaze started about 4:30 a.m. in the garage at 3502 W. 4490 South. Three cars were destroyed, including the trooper's patrol car. Flames also burned through the kitchen and living room, causing $80,000 damage.

More than 15 firefighters battled the blaze for several minutes before controlling it. No injuries were reported.

The second fire, at 3080 W. 4060 South, also started in the garage and swept through the house. It gutted most of the rooms, causing $100,000 damage. Salt Lake fire units responded about 4:52 a.m.

A neighbor saw the fire and helped evacuate the family, Battalion Chief Moose Barkdull said. No injuries were reported.

Barkdull said investigators had not yet determined whether gasoline or another fire accelerant was used.

Last month, a Salt Lake County deputy sheriff's patrol car was bombed. A note left near the car said the bomber was targeting law enforcement officials. "You've not seen and heard the last of us," the note read.
