Must read: Would-be hit man may have warned police before N.C. killing

CHARLOTTE, N.C. - Police may have ignored a warning years ago that a woman with five dead spouses was trying to hire a hit man to kill one of the men, investigators in North Carolina said Monday.

Authorities charged 76-year-old Betty Neumar last month with one count of solicitation of murder in the July 1986 death of Harold Gentry. Gentry's brother had begged investigators for two decades to take another look at the case.

Stanly County sheriff's investigators believe Neumar tried to hire several people to kill Gentry. Lead detective Scott Williams said Monday his office is looking into the possibility that one of those would-be hit men went to authorities before Gentry's death, but no one took him seriously.

'That's another aspect we're looking into,' Williams said, declining to elaborate.

Neumar has been married five times since the 1950s, but each union ended with the death of her husband. Investigators are urging police elsewhere to look into those deaths.

Williams said detectives believe Harold Gentry was Neumar's fourth husband. She and the third husband, Richard 'Dick' Sills, were living in the Florida Keys when he was shot to death in 1965, Williams said. At the time, police said his death was the result of a self-inflicted gunshot wound. But Williams said Neumar was the only person in the room when he died.

'They were having a terrible argument and apparently a gunshot went off and he's dead,' Williams said.

After his death, Neumar met Gentry in Florida. The couple married in the late 1970s in Georgia after he retired from the Army and moved to the town of Norwood, about an hour east of Charlotte.

Gentry was found shot to death inside the couple's home on July 14, 1986. Three years later, she married her fifth husband, John Neumar. He died in October, and authorities in Augusta are investigating whether his death - officially listed as listed as sepsis, bacterial infection of the body's blood and tissues - might have another cause, such as arsenic poisoning.
