Family members are mourning the loss of two Colorado men killed in a crash near Franktown just four days before Christmas.

Stephen Edwards, 70, of Peyton, and Jeffrey Lobato, 47, of Colorado Springs, were killed when their vehicles collided head on at mile marker 44 on Highway 83 around 5:30 p.m. Dec. 21. Three others were seriously injured.

Investigators with the Colorado State Patrol are looking at excessive speed as a possible factor in the accident.

An Audi S5 driven by Edwards was traveling northbound on Highway 83 when it crossed the double-yellow line and collided “left front to left front” with a southbound 2003 Chevy Tahoe driven by Lobato, said Trooper Josh Lewis, public information officer for the Colorado State Patrol.

Both Edwards and Lobato were declared dead at the scene. A 47-year-old female passenger in the Chevy Tahoe was transported to Parker Adventist Hospital with life-threatening injuries, and an 18-year-old female was taken to the same medical facility with serious injuries. A juvenile was transported to Swedish Medical Center with serious injuries. Their conditions are unknown.

Both drivers and all three passengers in the Chevy Tahoe were wearing seatbelts. Drugs and alcohol are not suspected as a factor.
