Police have told the Connecticut Post the boy took 50 packets of heroin out when it came time for a show-and-tell presentation, but Vallas said the boy only waved the heroin around at his cubicle. Police did not respond to messages seeking comment Tuesday.
The boy's stepfather, 35-year-old Santos Roman, went to the school and recovered the jacket, but police had already seized the drugs, officials said. He was arrested when he returned to the school after apparently discovering the heroin was missing, Vallas said.
