A 26-year-old Hicksville man was charged with manslaughter Wednesday for allegedly injecting a homeless man with heroin and causing him to die.

Police say Edward Plakstis sold heroin to 42-year-old Thomas Callahan and another man on May 23 and injected Callahan with the narcotic, causing his death. Officers responded to a call about Callahan having trouble breathing and arrived at the Hicksville train station shortly before he died.

Detectives say surveillance video from the station led them to Plakstis. He was also charged with two counts of criminal injection of a narcotic drug. If convicted, he faces up to 15 years in prison.
