Police are looking to question a person of interest in connection with the death of a man in Chelsea over the weekend.

Authorities released pictures, above, of the man they're looking for in connection with the death of 57-year-old John Laubach.

At this point police are not calling the man a suspect.

Laubach was found dead in his apartment Friday night. Sources say his hands, feet, and mouth were bound with duct tape, and there was a towel over his face. The apartment had also been ransacked.

A female friend found his body.

The medical examiner is still working to determine an exact cause of death.

Anyone with information is being asked to call the Crime Stoppers hotline at 1-800-577-TIPS.
