The 28-year-old rapper is one of the suspects in the slaying of a man in the city of Fort Lee last September and will remain held in lieu of bail on a judge's order, AllHipHop.com said.
Wingate allegedly learned that two men, Allan Plowden and David Taylor, had been flashing money and conspired with another suspect, Kevin Leerdam, to rob them in a New Jersey Holiday Inn.
Police suspect Leerdam and Wingate broke into the men's hotel room and fatally shot Taylor when he entered. They then allegedly bound Plowden and fled with an undisclosed amount of money.
The Web site said an attorney for the rapper claimed her client was not in New Jersey at the time of the crime.
