SAN ANTONIO – A fire that broke out in an abandoned house spread to a neighboring home on the West Side, causing heavy damage to both properties.

Firefighters responded just after 1 a.m. Wednesday to the fire on Lark Avenue near Broadview, where they found the abandoned home engulfed in flames. The fire had already burned through the roof, which later collapsed.

The flames spread to the occupied house next door, where two residents were able to escape safely. That home sustained substantial damage.

Crews called a second alarm to help battle the blaze. The abandoned house is expected to be a total loss, while the cause of the fire remains under investigation. No injuries were reported.
