GREELEY, Colo. -- A 16-year-old Berthoud, Colo., youth faced multiple charges Thursday in connection with an accident that claimed the lives of two friends.

The Weld County District Attorney's Office reviewed the May 25 accident, south of Berthoud, and issued a summons charging Benjamin Moden with two misdemeanor counts of careless driving causing death, two misdemeanor counts of careless driving causing injury, and several traffic infractions.

Shawtae Taylor, 15 and Kurtis Soeby, 18 were killed in the crash. Two other teenagers riding in the same car were injured in the crash.

They were in a 1991 Lexus that was traveling east on Larimer County Road 4 near Berthoud when the Lexus failed to yield the right-of-way at a stop sign, the CSP said. A 2003 Dodge Ram pickup truck traveling north on Weld County Road 1 slammed directly into the Lexus' passenger side. (See Images From Crash Scene.)

The pickup truck was driven by Leslie Mechem, 68, of Berthoud. He was treated at the accident scene and released.

The district attorney's office said that Moden was driving the Lexus. CSP investigators said none of the teens were wearing seat belts.
