Two fires in as many hours Wednesday morning in Beloit. The first fire was reported just before 3:00 a.m. at a home in the 1800 block of Saint Lawrence Avenue. Fire Lieutenant Keith Lynn says the resident was returning home when he discovered the fire. The cause is believed to be an electrical problem in the porch lamp. The second fire was reported just before 5:00 a.m. at a home in the 1400 block of Central Avenue. In that case, the alarm was not sounded by the resident or smoke detector. The dog began barking. The cause in that case is believed to be incense left burning on a computer table. Lynn says in both cases damage was primarily confined to the area of origin.
