Callie Noble Schwarzman, a 22-year-old Lutherville-Timonium woman, was still under supervised probation from a 2017 DUI arrest when police say she drove her SUV off the road in a residential Baltimore County neighborhood and struck 5-year-old Delaney Gaddis and 60-year-old Deborah Limmer while they were on a walk Monday morning.

Limmer had been pushing her granddaughter in a stroller on the sidewalk along Girdwood Road, near Dulaney High School, about 6:50 a.m.

Schwarzman now faces charges that include driving while impaired by alcohol and controlled dangerous substances, negligent manslaughter by automobile and homicide by motor vehicle while impaired by drugs and alcohol.

A representative of the Baltimore County state’s attorney’s office wrote in a July 23 letter to Carroll County Judge Brian D. Green that Schwarzman admitted to smoking marijuana, drinking alcohol and taking a Percocet tablet the night before Monday’s crash, court records show.
