MORE: Cruiser cam from stolen police car shows 3 minutes of traffic terror
Walters is charged with murder, involuntary manslaughter, aggravated vehicular homicide, felonious assault, robbery, aggravated vehicular assault, failing to comply with a police officer and other offenses.
He originally was due in court on Feb. 29, but appeared Thursday.
On Aug. 26, police and prosecutors say Walters stabbed his father multiple times, stole and crashed his father’s truck, stole a Riverside police cruiser and then crashed it in front of the downtown Dayton Metro Library while driving about 97 mph.
The cruiser struck a van, resulting in the deaths of two 6-year-old girls, cousins Penelope Jasko and Eleanor McBride.
