Isaac Balckhorse Garcia, the alleged driver, is being held on several charges including murder, sex with a minor and hit and run.

Garcia sped away, subsequently hitting the other sister with his car.
Detectives say Garcia was in a sexual relationship with both underaged sisters. They fear there could be more victims out there.
“Our detectives believe that it’s possible that he may have done this with other minors,” said Officer Ryan Railsbeck. “We are hoping that by putting his photo - his booking photo and another that if there are any young teenagers who had communication with him that could lead us to believe he was doing this to others.”

The victim he hit died at the hospital but her baby survived. Police say the child is in critical condition.
Garcia is currently being held at the Robert Presley Detention Center without bail.
