Authorities are investigating a suspicious fire that destroyed a home, causing about $100,000 in damage Sunday night.

The fire at 540 S. Main was reported by a next-door apartment resident about 8:30 p.m., said Midvale Fire Assistant Chief Lee Webster. Upon arrival, fire crews found the house completely engulfed in flames.About 25 firefighters from the Midvale, Sandy, Murray, West Jordan and Salt Lake County fire departments spent the next 90 minutes fighting the blaze before it was brought under control, Webster said.

"We set lines and made a good stop, but the house was totally engulfed," he said. "It looks like a total loss."

No one was in the house when the fire started, and no one was injured. A crew remained at the scene throughout the night, and the investigation resumed Monday morn-ing.

The 14-room house was the childhood home of former astronaut Don Lind, who was in the fifth astronaut selection under the Gemini space exploration program in 1966.

Because several of the later Apollo missions were canceled, however, Lind did not travel into space until 1985 as a member of the 17th Challenger space shuttle flight.

Lind, 67, of Smithfield, Cache County, lived at the home between his birth in 1930 and the time he joined the military in 1955, he said. His family sold the house in 1977.

"That was a wonderful place to grow up," he said. "It is a personal tragedy (that the house burned down)." Lind is now second counselor in the Portland, Ore., LDS Temple presidency.
