A 17-year-old Ohio boy pleaded guilty to multiple felonies, on Monday, including the 2022 reckless homicide of a 15-year-old girl.

Steven Fisher was expected to be tried as an adult this week, a year-and-a-half after the killing of Cleveland resident Jaiden Rose Rentas.

Cleveland Police discovered Jaiden's body in a still-running car, that had been abandoned in a field after her family initially said she was missing, WOIO reported.

Fisher was initially charged with murder, involuntary manslaughter, felonious assault, tampering with evidence, receiving stolen property, grand theft, offenses against a human corpse and improperly handling firearms in a motor vehicle.

In addition to reckless homicide, he pleaded guilty to possession of stolen property, grand theft and gross abuse of a corpse.

Fisher is expected to appear in court for sentencing on May 22.
