Salt Lake fire investigators believe a house that caught fire twice Tuesday night was ignited intentionally.
Just after 6 p.m. a Salt Lake police officer spotted smoke and flames coming from the second story windows of a house, 358 N. Redwood Road. After telling emergency dispatchers to contact the fire department, the officer found a witness who told him he saw two teenage boys riding away from the structure on their bicycles just before the fire started.
Fire crews knocked the fire down and thought they had put it out. Just before midnight, however, they were called back to the house when it caught fire again. Fire investigators were unsure Wednesday if hot spots from the first incident sparked the second fire or if it was intentionally set on fire a second time.
Because of the damage, the remains of the old structure, which had been vacant for a couple of years, were demolished due to being unstable following the two fires, according to the fire department. The old building posed a threat of crumbling and damaging a nearby apartment.
The search for the two teens seen near the fire continued Wednesday.
