SAC CITY, Iowa (AP) — A judge says a 17-year-old facing vehicular homicide charges in the deaths of two teenagers will be prosecuted as an adult. District Associate Judge Adria Kester says the 17-year-old does not have reasonable prospects of rehabilitation if he remains in juvenile court.

The Sioux City Journal reports the 17-year-old is charged with two counts of vehicular homicide in Sac County Juvenile Court. Court records do not yet indicate any filings in district court. Sac County Attorney Ben Smith will have several weeks to file additional information. The 17-year-old was driving a pickup that collided in August with a car driven by 16-year-old Bailey Jacobsen. She and her passenger, 16-year-old Lindsey Quirk, were killed.

Authorities say the 17-year-old’s blood alcohol level was above the legal limit for minors driving.
