I'm not sure why they think any of these might be Joel's, unless they don't believe he has told them about all of his victims? The ones that are still missing are all reportedly in the water.
Long Island serial killer
Joel Rifkin says he's not impressed by the fiendish handiwork of a murderer who dumped the bodies of four women near Oak Beach.
"I dumped them hundreds of miles apart," Rifkin proudly told the Daily News Wednesday in a 70-minute interview at the upstate prison where he will spend the rest of his life.
His victims were scattered in rivers and wooded areas from the east end of Long Island to upstate. Three were never found.

Rifkins missing victims...
He recalls killing one hooker named "Susie" in March of 1989 putting her into garbage bags and a paint can. Rifkin drove the body parts across the state line to New Jersey, dropping the head and legs
in the woods near Hopewell. (Quickly found by a golfer.) Doubling back from there, he returned to Manhattan, pitching the arms and torso into
the East River.
Another sometime in 1990, the victim was prostitute Julie Blackbird. Driving into Manhattan, he consigned Blackbirds head and torso to the
East River, then dropped her weighted arms and legs into a
Brooklyn barge canal. The remains were never found.
Rifkin could not recall the name of "number six," murdered a few days shy of Christmas 1991. He drove to a recycling plant in Westbury, where he had once worked part-time, and helped himself to a
55-gallon oil drum. There was ample room for Jane Doe in the barrel, safely hidden for their ride to the South Bronx, where Rifkin found a district rife with junkyards and
rolled her into the East River.
The 14 other victims
31-year-old Barbara Jacobs. Rifkin wrapped Jacobs in plastic, folded her into a cardboard box and drove to the
Hudson River, dropping her into the water near a cement plant.
Mary Ellen DeLuca, age twenty- two. From the motel, he drove upstate to Orange County and left DeLuca's body
at a rest stop outside Cornwall, near West Point.
Another 31-year-old victim, Korean hooker Yun Lee. Rifkin wedged Lee into the same trunk he'd used for Mary DeLuca and
dropped her in the Harlem River.
Lorraine Orvieto, age twenty-eight. Back at the landscaping lot, Rifkin stuffed her into an
oil drum, drove her body to Brooklyn and
dropped it into Coney Island Creek.
Maryann Holloman, age 39. He followed the same disposal procedure as with Orvieto: back to Long Island,
the oil drum and Coney Island Creek.
The oil drum was a new kink with Rifkin, used at least four times by his count. A Jane Doe victim, thus entombed, was
dredged from Newtown Creek, in Greenpoint, Brooklyn, on May 13, 1992.
With 25-year-old Iris Sanchez, strangled in May 1992, The site he chose was an illegal dump,
200 feet off Rockaway Boulevard, within sight of JFK International Airport. Rifkin wedged the body underneath a rotting mattress, first relieving Sanchez of her watch and other jewelry.
On May 25, 1992, he strangled crack addict Anna Lopez, dumping her corpse
in some woods off Interstate 84, in Brewster, New York.
Violet ONeill, a 21-year-old prostitute. Rifkin consigned her remains to the
waters surrounding Manhattan. Her torso surfaced in
the Hudson River, wrapped in black plastic, while her arms and legs were found in a discarded suitcase.
Mary Catherine Williams, 31. After a struggle to get the car started and moving, Rifkin drove Williams to
Yorktown, a Westchester suburb, where she was found on December 21, 1992.
Jenny Soto, 23 was the fighter, breaking all 10 fingernails as she clawed Rifkins face and neck. He rolled Soto into
the Harlem River, near the spot where Yun Lee had been found 14 months earlier.
Three months later, he killed Leah Evens, 28. He drove Evens to the
far eastern end of Long Island and
buried her in the woods, the
only one of his victims who rated a shallow grave.
The next to die, Lauren Marquez, was a 28-year-old addict and prostitute, Rifkin dumped her body in the
Suffolk County pine barrens, where she lay undiscovered until his arrest.
Rifkins last victim, Tiffany Bresciani, was another southern girl. He was on his way to dump the corpse
near Melvilles Republic Airport, some 15 miles north of his house, when Troopers Ruane and Spaargaren noted his lack of a rear license plate.
