SACRAMENTO (CBS13) – A woman was hurt after jumping from a balcony to escape a two-alarm fire at her south Sacramento apartment complex early Thursday morning, according to firefighters.

The fire broke out at a complex on Gloria Drive off 43rd Avenue just east of Interstate 5 after 7 a.m. Thursday.

“I heard some yelling,” neighbor Rosie Jauregui said. “I thought somebody was getting beat up.”

That noise was coming from a second-floor unit of the South Park Village apartments in Sacramento.

“I looked out the bathroom and smoke was coming out,” Jauregui said. “Flames were just coming out.”

Thick, dark plumes of smoke could be seen from miles away.

The apartment manager told CBS13 that two adults and two children were all inside one unit.

One woman had to jump from the second-floor balcony. She was transported to the hospital after injuring her legs. Two service dogs also died in the fire.

“It’s frightening,” Sacramento Fire Battalion Chief Jonathan burgess said. “Fire makes people do things they normally wouldn’t do.”

Firefighters say the cause of the fire is under investigation, but they did sent an arson team out.
