2 more rock-throwing incidents bring total investigated to 7, including 1 that killed Alexa Bartell

The Jefferson County Sheriff's Office said there have been two additional rock-throwing incidents added to the list of attacks from last Wednesday night, bringing the total number of known rock-throwing incidents that night to seven. One of those attacks took the life of 20-year-old Alexa Bartell. 

According to investigators, the additional attacks happened along Highway 93 near State Highway 128. The suspects would have been driving northbound at the time. 

Those attacks happened between 10:26 and 10:45 when Bartell was hit and killed. The incident involving Bartell is believed to have been the final incident of the night. 

Bartell was killed as she drove north on Indiana Street in the 10600 block last Wednesday night. A rock in the three-to-five-pound range came through the window killing her. Her friend found her dead in her car off the road.  

Alexa's death is believed to be linked to several other incidents in the area that same night. Two other people have minor injuries after rocks described as larger than softballs and ranging from three to five pounds came through their windshields.
