One woman is dead after an early-morning fire in a San Francisco apartment that displayed "evidence of hoarding," the San Francisco Fire Department says.

At 5:10 a.m. Friday, fire crews were called to a Parkmerced apartment building on Chumasero Drive, which is just off Brotherhood Way near the San Francisco Golf Club.

According to SFFD Deputy Chief Mark Gonzales, though the fire alarm for the entire 13-floor building had gone off, crews instead found several small fires burning in a single apartment.

Gonzales says that upon entering the unit, crews found a body, described by the Chron as a woman of unknown age or identity.

According to Gonzales, the apartment was crowded with possessions, suggesting a hoarding situation. In fact, according to Gonzales, the apartment was so packed that crews had to search for the flames before extinguishing the fire.

The deceased woman appears to have been the only resident of the apartment, and no one else was injured in the blaze. The fires remain under investigation.
