A woman has been killed by a rock thrown into her car as she drove.
Alexa Bartell, 20, had been speaking to a friend on the phone while driving but suddenly went silent on Wednesday (April 19) at around 10.45pm.
The concerned friend tracked her location on the phone to a point on Indiana Street, Arvada, Colorado.

When they arrived they found Alexa already dead in her yellow Chevy Spark.
The young woman had been fatally injured by the rock.
Shockingly, her death was the fourth of five similar incidents reported in the area from 10pm onwards on Wednesday.
Two other drivers who were targeted suffered minor injuries.
Police say they have a number of suspects and are continuing to investigate, as they appeal for anybody with information or dash cam footage to come forward.
They initially revealed they had located a truck believed to have been involved in the rock-hurling. However, they later said that suspect had been ruled out.
Jefferson County authorities have confirmed they found the rock that killed Alexa.
Spokesman Carlin Tilley said the rocks thrown at drivers appear to be ones used in landscaping.
Police also said they are to recommend murder charges when a suspect is located.
Jefferson County Sheriff’s Office said: "We are working with Boulder County Sheriff’s Office, Arvada Police and Westminster Police to gather information. We believe there may be more victims.
"Investigators need the public's help identifying and locating the suspects involved in these crimes.
"If you were in any of these areas and witnessed anything related to the suspect vehicle or the suspects who may have been inside, call the JCSO tip line at 303-271-5612. No piece of information is insignificant.
"If you have home security or dash cameras that may have caught the vehicle driving by, we want to hear from you."
