WWW- A Brooklyn go-go dancer who once appeared on “The Maury Povich Show” was identified yesterday as the mystery woman whose body was found stabbed, burned and dumped in a Canarsie marsh, police said.

As police hunted for Desiree Cherry’s killer last night, relatives charged that cops didn’t do enough to find the 36-year-old mom – even losing the missing person report they filed when she vanished last week.

“Perhaps she could have been found alive,” said Cherry’s sister, Glenda Cotter. “A lot more could have been done.”

Cherry’s naked, charred body was found Saturday at Fresh Creek Park.

She disappeared Tuesday night and family members reported her missing Wednesday, but 71st Precinct cops told them they had to wait 48 hours to make a report, the family said. Relatives filed an official report Thursday, but they allege cops misplaced the paperwork and contacted them that day to redo it.

“That’s a bit of time the police had to investigate,” Cotter said. “I want whoever did this to our sister to be captured and punished.”

An NYPD spokesman said he was not aware of a misplaced report in the case.

On the night Cherry disappeared, some pals told detectives she left her Schenectady Ave. apartment at 10:30 p.m. to go to her favorite club, East New York’s Elite Ark, and asked a neighbor to watch her 14-year-old son.

But Cherry, who regularly went dancing at the bar on “Nasty Tuesdays,” did not show up that night, Elite Ark bar manager Robert Earl said.

The last incoming call on Cherry’s cell phone came just after 10:30 p.m. Tuesday from a pay phone, sources said.

Using the stage name Shai, Cherry supported her son Arrkim by dancing at Richmond Beer Garden, a go-go bar in Plainfield, N.J., on weekends.

“She kept to herself, and she was beautiful and she was a good dancer,” said bartender Cookie, who declined to give her last name. “It’s horrible.”

In the past year, Cherry went on “Maury” and posed as a boxer in a stunt where the audience was asked to guess whether she was a man or a woman.

Sources said cops are looking at the men in Cherry’s life – those she dated, and a creepy patron who had been stalking her since her previous job at Cinderella’s Go-Go Palace in Elizabeth, N.J. Her son’s father, Dennis Joseph, was killed by stray gunfire in Brooklyn 13 years ago.

“She couldn’t walk down the street without people stopping to look at her,” said pal Donya Small. “A lot of guys wanted her. … A lot of girls wanted her, too.”
