Cause of house fire remains unknown
The fire at 1608 S. Willard Ave. started in the attached carport between the garage and two-story house, but the cause still was undetermined late Monday afternoon, according to a department press release.
In addition to the $100,000 damage to the garage and house, the fire caused $50,000 damage to contents, according to the release.
Twenty-three firefighters, six engines and two ambulances responded at 1:59 a.m. Monday to the single-family dwelling owned by Tanelle Nelson, according to the release.
When firefighters arrived, Nelson and Jason Kaltenbach and two dogs already had evacuated the house. Two cats later were found dead inside, according to the release.
When Kaltenbach woke just before 2 a.m., he found fire at the rear of the second story. There were no smoke detectors in the house, the release said.
The blaze caused extensive fire and smoke damage to the house and garage, according to the release.
Janesville police and Alliant Energy also assisted at the scene.
