Thousands of marchers and a rainbow of floats filled the streets of New York Sunday as the city celebrated gay pride, one of a full weekend of events marred by a shooting death Saturday at a street party in San Francisco.

Participants in New York’s annual parade, including Mayor Michael Bloomberg and Gov. David Paterson, made their way down Fifth Avenue toward Greenwich Village. Throngs of people turned out despite the heat and humidity on Sunday to watch the city’s annual parade celebrating gay pride.

This year’s parade has three grand marshals, including Constance McMillen, the lesbian teenager who sued her Mississippi school district over its policy banning same-sex prom dates.

San Francisco’s 40th annual gay pride weekend started Saturday at Civic Center Plaza, where thousands converged as vendors sold barbecue and burritos and DJs spun tunes on a large stage. The party later moved into the city’s Castro District for the “Pink Saturday” street party, where police said a 19-year-old man was killed and two others injured in a shooting late Saturday.

It wasn’t immediately clear if the violence had anything to do with the gay pride festivities.

Stephen Powell died early Sunday, said James Fiorica, an investigator at the Medical Examiner’s Office. Powell was shot in the chest.

A 19-year-old man was arrested and a handgun was recovered, said Officer Samson Chan, a police spokesman.

The name of the suspect was not released.

A 19-year-old woman and a 29-year-old man were shot in the legs but are expected to survive, Chan said.

Thousands gathered Sunday to watch and participate in the city’s gay pride parade. The Backstreet Boys were due to perform and U.S. House Speaker Nancy Pelosi, who is from San Francisco, was scheduled to deliver a videotaped address to revelers.
