A fire near downtown San Antonio killed three puppies and forced a family out of their home early Tuesday morning.

San Antonio firefighters responded to the fire around 2 a.m. at a home on Gus Garcia.

Fire officials said residents heard noises outside and noticed a fire on the porch. The fire quickly spread to the attic and then two rooms inside the home.  

A married couple and their baby were able to get out safely, but said three puppies they were training as service animals died.  

Firefighters said there were a total of five dogs in the home and two were saved. The husband made at least one attempt to get the puppies, but was unable to save them.

The wife tells KSAT she initially thought someone was breaking in and then could hear someone starting the fire.

She said a stranger helped her and her baby climb a fence after they escaped through the back door, but then disappeared.

Fire officials said people were seen running from the area, but it was unknown Tuesday morning if anyone had been arrested in connection with the fire.

Arson investigators determined the fire was started by some sort of incendiary device, possibly a Molotov cocktail.
