JEFFERSON COUNTY, Colo. — The man suspected of starting a large fire at a Jefferson County apartment complex has been charged with a number of counts, including attempted murder and arson.

Alex Duran, 29, was arrested Saturday after the structure fire in the 8400 block of South Reed Street.

Duran resided in the six-unit condominium building where the fire was located.

When deputies arrived at the scene early Saturday morning, the building was fully engulfed in flames and it was reported that people were still inside.

South Metro Fire Rescue and West Metro Fire Rescue were both on the scene and worked together to extinguish the fire.

One deputy and one firefighter were taken to the hospital and treated for injuries in connection with the fire.

All residents of the building have been displaced as the building is currently uninhabitable.

Duran was taken into custody, interviewed and booked into the Jefferson County Jail on 12 counts of attempted first-degree murder, six counts of first-degree arson, nine counts of second-degree arson, 18 counts of fourth-degree arson, criminal mischief and third-degree assault.
