The New York City medical examiner says autopsy results are inconclusive for a fashion designer found floating on the Manhattan side of the Hudson River.

The medical examiner's office said Monday that more tests are needed to determine the cause of 55-year-old Michele Savoia's death.

His body was discovered off Chelsea Piers on Sunday afternoon, not far from where he lived aboard his boat.

It wasn't clear how Savoia ended up in the river, but police do not suspect foul play. He was last seen alive leaving a nearby nightclub early Thursday morning.

Savoia reportedly designed hand-crafted suits for celebrities and had a boutique on the Lower East Side.
