WEST JORDAN, Utah — A fourth person has died as a result of a house fire in West Jordan Friday morning.
Sgt. Andrew Hercules with the West Jordan Police Department said three people were found dead inside the home when crews arrived at the home located near 6400 West and 8100 South. They included one adult man, one adult woman, and a juvenile male of unspecified age.
A juvenile female was found outside the home and airlifted to the hospital with critical injuries. She later passed away.
In an update Saturday, police said they believe the fire was arson and was started by one of the deceased individuals. Fire investigators reportedly determined that an accelerant was used.
The identities of the deceased have not yet been released, but police said they appear to belong to the same family.

Video sent to FOX 13 News shows a man, identified as 20-year-old Asher Nelson, jumping from his car and rushing toward the house, jumping a fence, to help someone who was seen escaping the house fire.
Nelson is being treated for smoke inhalation at the hospital, according to his family.
"A lot of concerned neighbors, a lot of people who attempted to help the family and help everyone who was involved — we’d like to thank those people for those brave actions and what they did,” Hercules said.
Significant damage could be seen on the upper level of the house.

A neighbor told FOX 13 News that she heard a large explosion while she was eating breakfast, but believed it was simply an ordnance demolition that had been taking place in recent weeks.
