The following a list of some of the longer unsolved cases in Atlantic County:

KIM RAFFO, TRACY ANN ROBERTS, BARBARA BREIDOR, MOLLY JEAN DILTS: On Nov. 20, 2006, four women were found in a ditch behind the marsh off the Black Horse Pike in the West Atlantic City section of Egg Harbor Township. Kim Raffo, 35; Tracy Ann Roberts, 23; Brabara Breidor, 42; and Molly Jean Dilts, 20, were eventually identified, and it was determined they had died at different times. A cause of death could be determined for only two of the women. All four had worked at prostitutes in Atlantic City. Three of the four had a lot of drugs in their system, but it was drugs they were known to have used. DNA tests were done on Salem County resident Terry Oleson, who had been staying at a motel near where the bodies were discovered, but he was never named a suspect, and no charges have ever been filed in the killings.

RONALD WASHINGTON: Video surveillance outside Wash’s Inn in Pleasantville shows a man walk up behind Ronald Washington, 27, and fire four shots into his back at about 1:30 a.m. Nov. 14, 2007. At least eight people witnessed the shooting, some walking around him as the mortally wounded man struggled to get into the bar. No arrests were made.

JOYCE McKINNON: Joyce McKinnon, 61, was in her Venice Park bed when she was fatally shot Dec. 11, 2009. Three days earlier, Jamal Smith, 19, was killed in Pleasantville. The man eventually convicted of killing Smith was Sellers Ingram, her daughter’s boyfriend who had been living at McKinnon’s home. Her daughter, Veronica Grant, believes her mother was shot in retaliation. A man told her he saw the killer, but is afraid to come forward, she said.

QUINTIN PRATER, ERIC PRATER, SALEEM TOLBERT: Eric Prater, 30, was fatally shot July 13, 2010, in the 1000 block of Magellan Avenue in Atlantic City, one week after Saleem Tolbert, 26, was shot around the corner. Prater was the second of his mother’s sons to die in Atlantic City’s gun violence. Fourteen months earlier, on May 24, 2009, Quintin Prater, 24, was killed in the 800 block of North Virginia Avenue. No arrests have been made in any of the killings.

KONSTANTIN KRAEV: Russian citizen Konstantin Kraev, 22, was working his second summer in Atlantic City when he decided to walk his friend — another Russian worker — to her friend’s home because he worried about her safety. After dropping the 19-year-old woman off at the home on Arctic Avenue near the New Jersey Avenue School, he was fatally shot in an apparent robbery. No one has been charged.

QUADIR LAMPKIN: Quadir Lampkin, 19, was being driven home to Atlantic City from a party at the Cologne Firehouse in Hamilton Township on May 28, 2011, when another car came along as they drove along the White Horse Pike in Galloway Township. Then the shooting began. Lampkin was killed. The driver, Habibah Abdullah, was wounded. Lampkin’s mother, Ronda Lampkin, believes people know who killed her son — who went by the nickname “Quack” — but are afraid to come forward. “It is clear that (Quadir Lampkin's killing) was not a random act of violence," then-Atlantic County Prosecutor Ted Housel told The Press of Atlantic City last year. "“People need to come forward and tell the truth.”

APRIL KAUFFMAN: The news that popular local radio personality and veterans advocate April Kauffman, 47, was shot to death inside her home on May 10 of last year rocked the normally quiet city of Linwood. It was just the second murder in at least 40 years. In 2009, a woman was stabbed to death by her neighbor who was later found not guilty by reason of insanity. But in Kauffman’s case, friends and family are still waiting for someone to be charged.
