Fire crews worked quickly to put out a house fire early Tuesday morning in southwest Bexar County.

The fire broke out just before 4 a.m. at a house on Quesenberry Road just south of Fischer and Somerset Road.

Firefighters initially thought the homeowner was inside but found out he was the hospital the entire time for an unrelated medical issue.

No injuries were reported. Damage estimates or a cause of the fire were unknown Tuesday morning.
