After the crash, Solis backed the SUV into an adjoining gas station parking lot and fled. His passenger, Elvis Hernandez, 28, was left with severe head injuries, and was taken to Rush Copley Medical Center.

The 34-year-old Chicago man who was driving the box truck hit by Solis was not injured.

Solis returned to the scene 45 minutes later, and was identified as the man who fled.

He is charged with driving under the influence of drugs, leaving the scene of a personal injury accident, driving without a suspended license, and driving without insurance.

Hernandez died over the weekend.

Aurora police are working with the Kane County State’s Attorney to pursue upgraded charges on Solis.
