About two hours before a 4-year-old was found lying on a neighborhood street in Dallas, a man lifted the sleeping boy from his bed and carried him away, court documents say, citing home surveillance video.

The boy, whom authorities identified Monday as Cash Gernon, was being taken care of by the girlfriend of Cash’s father, according to authorities. The girlfriend, who said Cash’s father had been absent since March, identified the person who took Cash from his bed at 5 a.m. Saturday as Darriynn Brown, police said.

A police detective watched the home surveillance video with the girlfriend, who identified Brown as the man who took the boy from his crib, according to the detective’s arrest affidavit obtained by The Dallas Morning News. The affidavit does not detail Brown’s relationship to Cash’s family or offer any explanation for Brown taking Cash.
