Three people were injured, one critically, around 8 p.m. Friday after falling from the second-story roof of a Magna home.

Unified Fire Authority spokesman Capt. Jay Fearnley said a woman in her 60s received head injuries and was airlifted from the scene in critical condition and arrived at University Hospital unconscious.

A man in his 40s was also transfered by helicopter and taken to Intermountain Medical Center with a severe lower leg fracture. The third injured person, a woman in her 40s, suffered two ankle fractures and was transported by ambulance to IMC.

Fearnley said details were still hazy, but he believed that the three were working on a reroofing project when one person started to slide off the roof. When the other two attempted to help, all three ended up falling onto a concrete driveway in front of the house, located near 2500 South and 8000 West.

All three remained hospitalized late Friday.
