The Police Department Internal Affairs Bureau is investigating how a police security video that captured a young man's suicide ended up on a Web site devoted to violence and pornography, a department spokesman said yesterday.
The young man, Paris Lane, 22, of Harlem, used a 9-millimeter handgun to kill himself on March 16 in a lobby at the Morris Houses project in the Bronx, where he had been visiting his girlfriend.
His foster mother said yesterday that she had notified the police when she learned the video had been posted on the site.
The 45-second video, which is no longer displayed there, shows Mr. Lane and his girlfriend standing near an open elevator door. She pulls her hands across her face as if wiping away tears and kisses him briefly, then they hug for a long moment, until she gently pulls away and steps into the elevator.
Mr. Lane waits for the elevator door to close, stares at it for a second, then pulls out the gun, puts it in his mouth and fires once, falling to the ground.
The site, Consumption Junction, describes itself this way: ''Sociopathic surfers have declared this free site the best place to get their fix of sick free adult humor, tasteless (but way funny) dirty jokes, and free video clips that include shocking moments, brutal stupidity, and a healthy dose of hardcore sex.''
It says it does not pay for the materials, which are sent in by its users, but it gives an award for one submission each month. The more printable video titles were, ''The Beer Helps You Lower Your Standards a Little'' and ''His Air Bags Didn't Inflate.''
The video of Mr. Lane's death was labeled ''Introducing: The Self-Cleansing Housing Projects.''
Mr. Lane's foster mother, Martha Williams, 56, called the Web site racist. She said she began receiving calls on Sunday from people telling her that the video, which does not identify him, was on the Internet. She said she had looked to confirm it was true, but could not watch it.
She went to C. Virginia Fields, the Manhattan borough president, for help. A spokeswoman for Ms. Fields said Ms. Williams had previously asked the police if she could view the video, but had been denied.
Ms. Williams said the video's appearance on the site ''desecrated'' the memory of her son.
''I just started back to work. I started healing, and this kicked me backwards. My whole body was shaking,'' she said.
