State police have arrested a New York City man on murder charges in an unsolved 1984 Long Island stabbing.
That killing appears to have been in retribution for a homicide that occurred years earlier.
The suspect arrested Wednesday is 46-year-old Raed Innab. He was ordered held without bail after pleading not guilty at his arraignment on a second-degree murder charge. A call to his attorney was not immediately returned.
Shortly before his death in 1984, victim Darwish Ali Darwish had completed a seven-year prison term for first-degree manslaughter in Carl Innab's death.
Raed Innab is the nephew of Carl Innab.
Police did not immediately have details on that case.
Darwish was stabbed numerous times along Hecksher State Parkway in East Islip.
Investigators say scientific advancements led to Wednesday's arrest.
