EL PASO COUNTY, Colo. -

The Colorado State Patrol says its investigation into a crash that killed two teenagers and put a third in the hospital is moving forward.

The crash happened just before 1:15 a.m. Monday (9/1/14) at the intersection of Hodgen Road and Roller Coaster Road.  That's in northern El Paso County.

State Patrol says a 2009 MINI Cooper convertible was speeding eastbound on E. Baptist Assembly Road when the driver ran a stop sign at Roller Coaster Road.  The car went airborne, lost control and spun off the north side of the road, through a ditch and hit a tree.

Investigators with the Colorado State Patrol said they had mapped the crash site and were beginning the process of reconstructing it by midday Tuesday (9/2/14). They also said that they were planning to execute a number of search warrants, including one on the vehicle that was involved in the crash. 

Two passengers, 17-year-old Beau Begier of Monument and 18-year-old Ryan Pappas also of Monument, were pronounced dead at the scene.  State Patrol says Begier was not wearing his seatbelt and was thrown from the car.

A third passenger, Mitchell Clark, 17, from Monument, was wearing his seatbelt and suffered serious injuries.  He was flown to a local hospital.

The driver, a 17-year-old male from Parker, was wearing his seatbelt.  He had minor injuries and was taken to Penrose Main.  After he was released, he was arrested and taken to a juvenile detention facility where he is currently on a no bond hold. The teen appeared before a judge for the first time on Tuesday.

State Patrol says alcohol and high speed are considered to be factors in the crash.

State Patrol is seeking charges against the driver, including vehicular homicide and vehicular assault. The District Attorney's Office is expected to get the case in about a week. It will be up to the DA to determine what charges will be filed and whether the teen will be charged as an adult.
