A Rhode Island man who was charged with the gruesome murder of an Attleboro resident last summer might also have killed a Providence man in a similar manner.

Television station WPRI in Providence reports on Friday's indictment:

A grand jury indicted Matthew Gumkowski on murder and arson charges in the May 2011 death of 41-year-old Michael DiRaimo.

Firefighters found DiRaimo stabbed to death as they responded to a fire at a Providence home.

The Bristol County District Attorney's Office charged Gumkowski with first-degree murder, arson and armed robbery last July, 10 days after 50-year-old Joseph Kilrow was found stabbed, strangled and with his throat slashed on the floor of his room in an Attleboro rooming house. The room had been set on fire. Gumkowski, who was out on probation in Rhode Island, pleaded innocent and is awaiting trial in the Attleboro murder case.

Gumkowski was later charged in connection with an unrelated July 2 robbery of a woman outside Seabra on South Main Street. The woman told Attleboro police she had recognized his photo when he was initially named a person of interest in Kilrow's murder.
