On Tuesday, April 25 – Wednesday, April 26, Jefferson County Sheriff’s investigators arrested three suspects in connection with the death of 20-year-old Alexa Bartell. Alexa died Wednesday, April 19, at approximately 10:45 p.m. while driving northbound in the 10600 block of Indiana Street when a rock struck Alexa’s windshield. A spree that started at Sims at 100th and Westminster just after 10:00 that night.
Since then, JCSO investigators – with assistance from Westminster Police, Arvada Police and the Boulder County Sheriff’s Office – have worked around the clock to identify and arrest the suspects responsible for Alexa’s death. Joseph Koenig (DOB 9/11/04), Nicholas “Mitch” Carroll-Sick (DOB 10/17/04), and Zachary Kwak (DOB 3/18/05), all 18, were taken into custody at their homes. Arvada.
While it is unclear at this time which suspects were driving throughout the spree, the suspect vehicle is a black 2016 Chevy Silverado. All three are suspected of throwing the rocks, and all three now face charges of first-degree murder and gross negligence. Additional charges are expected to be filed and the First Judicial District Attorney’s Office will determine final charges. Mugs are not available at this time.
JCSO appreciates the local media, Metro Denver Crime Stoppers and the public for their interest and assistance in this case. At this time, JCSO is not seeking additional tips. Ultimately, mobile device forensics and public support information helped identify and arrest the suspects. A public information officer will be available for media interviews at 8:00 a.m. today at the Sheriff’s Office, 200 Jefferson County Parkway.
Investigators were pleased to be able to notify Alexa’s family and other victims of these arrests. This week’s recognition of crime victims’ rights reminds us of the courage and resilience of crime victims, including the Bartel family. They are our inspiration.
