Police say Thomas Gilbert was shot in the head in his Manhattan apartment on Beekman Place on the East Side. He was pronounced dead at the scene.

Police are seeking the gunman.

Gilbert founded Wainscott Capital Partners Fund in 2011. The fund has $200 million in assets and focuses on the biotech and health care industries.

Gilbert previously co-founded Syzygy Therapeutics, a biotech asset acquisition fund.

The shooting was a rare act of violence on Beekman Place, a tony enclave just north of the United Nations.
