Prosecutors have added a homicide count against a man accused of crashing his car into a river, killing a teen girl in Western Iowa.
Ramon Hernandez now faces vehicular homicide, drug and alcohol charges in the case.
Investigators believe Hernandez drove through a farm field with three other teens in the car and then slammed into the Boyer River in Denison last month.
Crews searched for 15-year-old Yoana Acosta for several days. They found her body last week.
