Arson investigators looking into cause of fire that destroyed 2 homes on West Side

San Antonio arson investigators are taking a close look at a fire that destroyed two homes on the city’s West Side early Monday morning.

What was supposed to be a vacant house went up in flames and then spread to a home next door.

The fire was called in around 2:45 a.m. on Monterey Street near South General McMullen.

Firefighters said when they arrived, they found a total of three structures on fire. The house where the fire originated had been occupied by the homeless, fire officials said.

The fire spread from the vacant house to a neighbor’s house and a shed also caught fire. Two people were displaced as a result of the flames.

Firefighters said they had reports of a homeless man still inside, but they searched and did not find anyone. The residents of the main house got out safely and are now staying with neighbors, fire officials said.

A neighbor said it appeared that someone set fire to the home, and she believes she caught the act on surveillance video.

An arson investigation team has since been called out to determine the exact cause.
