A body found by a New Jersey fisherman last month was that of artist Jeremy Blake, the New York Police Department confirmed Tuesday.

Police believe Blake, 35, committed suicide on July 17 by drowning himself at Rockaway Beach in Queens. He disappeared a week after his girlfriend, filmmaker Theresa Duncan, 40, committed suicide in their East Village apartment.

Blake, who worked as a graphic designer for a video game manufacturer, was considered a rising star in the modern art world. An abstract painter and video artist, his work has been exhibited at New York's Museum of Modern Art, the Whitney Museum of American Art and the Los Angeles Museum of Contemporary Art, among others.

His body, found July 22, about four miles off the New Jersey coast, was identified through dental records, said NYPD spokesman Paul Browne.
