A Malden man is behind bars for allegedly sodomizing a child. Investigators say the child’s mother said 44-year old Chad Cobb was watching her son while she was at work. When she got home her son was crying because he’d wet his pants. The child said he was crying because Cobb had put his genitals in the boy’s mouth. Court documents show that the child also had a busted lip. When asked how his lip got hurt, the boy told investigators that Cobb threw him on the bed in his bedroom. Inside the home investigators found marijuana, 2 packages of rolling papers, and 2 partially smoked marijuana cigarettes on the floor of the child’s bedroom. Cobb faces a felony charge of statutory sodomy.
