A North Bellmore woman stabbed her ex-husband to death in their home and dumped his body 30 hours later along the Wantagh State Parkway, State Police said Saturday.
Police said a "domestic incident" led to the stabbing around 10 p.m. Wednesday.
"We believe the victim never received medical attention and passed away sometime Thursday," Lt. William Hulse said.
Nancy Boland, 56, was arrested and charged with first-degree manslaughter, evidence tampering and criminal possession of a weapon.
She was arraigned Saturday afternoon in First District Court in Hempstead. She remained in jail Saturday night in lieu of $100,000 cash bail.
Walter Boland, 58, died of a single stab wound to the abdomen, police said.
The Bolands, while divorced, had been living together at the home on Waltoffer Avenue, according to police.
Authorities didn't know whether the couple had any children.
A woman who answered the phone at the couple's address hung up when a Newsday reporter called seeking comment.
Police said Nancy Boland loaded the victim's body in her Toyota Camry about midnight Thursday and some time later began driving around looking for a dumping spot.
About 4 a.m. Friday, she left the body on a bike path off the parkway, just north of Sunrise Highway, police said. A jogger made the grisly discovery four hours later, authorities said.
Police said the case remains under investigation and would not say what prompted the dispute that led to the stabbing.
Court papers say Nancy Boland tampered with evidence by disposing of a "sharp instrument" in her household trash.
A State Police senior investigator, John Lang, said the victim was identified through fingerprints.
Lang said Nancy Boland confessed to the crime when questioned by investigators.
She has two pending misdemeanor charges, third-degree assault and fourth-degree criminal mischief, according to court records.
Both cases are being heard in the domestic violence part of the court system.
Walter Boland, who filed for bankruptcy protection in 2005, has an extensive criminal record dating to 1991, including convictions for drug possession, possession of stolen property and drunken driving.
In 2009, he pleaded guilty to DWI and was sentenced to 9 months in jail, according to court records.
Authorities ask that anyone with information call State Police at 631-756-3390.
