Investigators are still trying to figure out what started a two alarm fire at the Cobblestone Ridge Apartments on the southwest side of Colorado Springs. The two-story complex started on fire around 2:15 Saturday morning at 4140 Pebbleridge Circle.

On Sunday, some residents were let back into their apartments. 8 Units were evacuated for about 24 hours after the fire. Those units were not damaged by the fire, but they are in the same building where 8 other units were heavily damaged.

11 News was first on the scene as people started evacuating and running for safety from the fire.

Eight apartments were badly damaged, displacing eight famlies. Everyone escaped safely. Two were taken to the hospital for minor injuries. Firefighters also rescued a dog inside.

The extent of the damage is still unknown.

The glow of orange and red is a familiar sight for Colorado Springs fire fighters. This apartment fire is the third blaze in less than 24 hours to call out multiple crews. "Had a lot of fire coming from the top floor going through into what looked like the roof at that time," says Lt. Jeff Sievers of the Colorado Springs Fire Department.

For Jacob Layba, it was a quiet night until a few hours later. "Got up and looked out the window and whole balcony was engulfed in flames rising above the roof about 20 feet," says Layba.

He noticed the chaos as those who lived here ran for safety. "There's people running around trying to get people out of the apartments," says Layba.

Firefighters say because the residents evacuated quickly, that's what saved their lives.

Fire crews remind all of us to check the batteries in your smoke detectors and have an escape plan.
