A Maryland State Police K-9 officer is receiving praise after the bloodhound tracked down a missing child with autism during Sunday’s winter storm. “We got a call for a critically missing child, (a child with autism), that left his residence without his guardian knowing,” Bel Air Police Department Chief Charles Moore said. “Subfreezing temperatures, snow — very deep snow, we had a lot of concern,” Moore told WBAL-TV 11 News. The community was helping, Harford County Sheriff’s Office (and) state police.”Moore said senior trooper Taylor Bracken and his partner, K-9 Margo, were nearby and came to help. Officers credited the safe finding of the teen to K-9 Margo.
