JEFFERSON COUNTY, Colo. (KDVR) — Multiple law enforcement agencies are looking for the suspects who may be responsible for a string of crimes from Wednesday night that resulted in the death of a 20-year-old after she was struck and killed by a large rock while driving.
The crimes occurred on Wednesday night starting at 10 p.m.
According to the Jefferson County Sheriff’s Office, 20-year-old Alexa Bartell of Arvada was driving northbound near the 10600 block of Indiana Street. JCSO believes the suspects threw a large rock either from a vehicle or the side of the road at Bartell’s car.
The rock allegedly hit Bartell, and she was killed.
Moments before she was killed, Bartell was on the phone with a friend when the call went silent. JCSO said Bartell’s friend tracked her address and found her dead inside her car that was off the roadway in a field.
This was not the first instance of rocks being thrown at cars that night.
According to JCSO, they believe this was part of an overnight crime series that involved a light-colored pickup truck or SUV.
