Exactly how and what started the fire will be determined by arson investigators collecting evidence, authorities said.
An off-duty San Antonio firefighter was among the first to respond to the blaze. On his way home from work, the man tried to battle the fire with a water hose until crews arrived, the report said. By the time units arrived around 11:45 a.m., they found the one-story residence engulfed in flames.
He “wanted to kill himself or hang himself,” the report said.
The boy was detained and taken to a local hospital for a mental evaluation, where he remained on suicide watch Thursday afternoon, authorities said.
