Bartell, of Arvada, was killed late at night on April 19 when a rock crashed through her windshield as she was driving on the 10600 block of Indiana Street close to the Jefferson County and Boulder County lines. Her vehicle left the roadway and ended up in a field. She was on the phone talking to a friend when she was struck and the phone went silent.

Two other people were also hurt in earlier rock attacks that night. Seven vehicles in total were hit by what authorities now describe as "large landscaping rocks." It's believed the suspects were in moving vehicle when the rocks were thrown.
