"Bloody rags and blood-stained clothing" were discovered at the Manhattan apartment building where a missing Connecticut man was last seen.

Stamford resident and Hofstra graduate Joseph "Joey" Comunale, 26, was last seen on Saturday night at 418 East 59th Street; his father reported him missing on Tuesday morning.

Police sources told the Daily News that Comunale was seen at the Grand Sutton tower apartment building on Saturday night, accompanied by three women and two men from New Jersey. The group was reportedly attending a party hosted by the son of "a well-known jeweler" who resides in the building.

Around 6:30 p.m. on Sunday, long after the women were reportedly seen leaving, the host allegedly requested a luggage cart from the front desk. According to the News, video surveillance showed a man "wheeling out two pieces of luggage."

The resident, WCBS 2 reports, "asked a doorman how long surveillance videos are kept on file."

The police brought in search dogs last night, and a garbage bag with bloody clothing were found near the building. The luggage cart may also have blood on it.

The building resident is being questioned by police now. A neighbor said, "It’s a very, very normal building and very, very nice people in general that live there, so I’ve never heard of any issues of this kind."
