FREDERICK, Md. - A 15-year-old boy was killed Saturday night in a Frederick town house fire that allegedly was set by his autistic twin brother, according to a press release from the Maryland State Fire Marshal.
Jerrell Williamson was killed when the fire broke out Saturday at 11:23 p.m. in the second-floor bedroom that the autistic twins shared at 6734 Sandpiper Court in Frederick, according to the release.
Jerrell's twin brother, Joshua Williamson; their mother, Carolyn Stone; and her boyfriend, Raymond Pullian, escaped the blaze, according to the release.
Fire marshals said Joshua Williamson had a history of setting fires, and they determined he ignited his own bed with a lighter.
