The caller was reporting a “2 door sedan” was “slowly rolling” in the area with two males checking doors on unoccupied vehicles. The caller provided the intersection of Blacktail Crest and Culebra Rd. Deputies proceeded to the general area and began to search for any suspicious vehicle/persons. While traveling southbound on Mountaineer Way, a deputy observed two individuals wearing dark clothing, running towards a vehicle. The two males entered the vehicle and began driving north bound on Blacktail Crest without utilizing their headlamps. Another deputy, traveling southbound on Blacktail Crest, located the suspect vehicle traveling on the roadway without any headlamps and attempted to contact the vehicle’s driver. The deputy proceeded to turn his fully marked BCSO vehicle around, activating his BCSO fully marked vehicle’s red and blue emergency lights, and began traveling northbound on Blacktail Crest. The deputy reported, via the radio, the suspect vehicle’s direction of flight was towards Culebra Rd and reported via the radio he had lost sight of the vehicle. A third deputy approached and stopped for a stop sign at the intersection of Blacktail Crest and Snowy Egret Fall, located ahead of the first deputy. The suspect vehicle was observed crossing the deputy’s path without any headlamps on and at what appeared to be a high rate of speed. The deputy proceeded to follow the vehicle and did not activate his red and blue emergency lights on his fully marked BCSO vehicle in order to “catch up” to the vehicle. As the third deputy continued to attempt to “catch up”, he approached debris on the roadway and a single vehicle collision (suspect vehicle) to include two decedents (driver and passenger—there were no other Custodial Death Report :: Page 6 of 7 --- PAGE BREAK --- occupants). During the investigation, it was found both decedents were utilizing a stolen vehicle that was taken prior to the collision. Additionally, it was found the vehicle’s approximate speed was found to be in significant excess of the posted 30 mph speed limit. Custodial Death Report :: Page 7 of 7
