One person is dead and a second injured, after an early-morning fire broke out in a home near Glen Canyon Park.

According to the San Francisco Fire Department, the blaze at 44 Molimo Drive was reported at around 4:20 Sunday morning.

According to NBC Bay Area, "neighbors quickly ran out to see if they could help calm the blaze but found 20 to 30-foot flames engulfing the structure for about ten minutes."

When they arrived on the scene, firefighters were met with "heavy fire blowing out of the front of the building," San Francisco Fire Department spokesperson Lieutenant Jonathan Baxter said.

"The whole front of the house had flames coming out the front," neighbor Daniel Homsey, told NBC Bay Area. "People had fire hoses, trying to suppress the fire and stop it from spreading to the homes nearby."

That combined effort was successful, the Chron reports, as by 6 a.m. firefighters had contained the blaze and "prevented the flames from spreading to neighboring homes."

However, the SFFD says that one adult was killed in the blaze, their body found on the first floor of the home. According to NBC, they were "killed trying to escape from the front of the home which was engulfed in flames." As of publication time, they had not been publicly identified.

The homeowner managed to escape from the rear of the two-story home, NBC reports. According to Bay City News, that person was injured in the fire but is is stable condition at an area hospital.

According to the SFFD, the cause of the fire remains under investigation.
