New Jersey investigators believe a man slit his wife's throat while she was driving, causing a crash, and then fled to a diner where he was found partially dressed and covered in blood.

The Burlington County prosecutor says Delran police responded Thursday night when a car collided with other vehicles. Police reported finding a knife in the vehicle and 54-year-old Cynthia Fortune on the ground with lacerations on her neck. She later died.

Her husband, 37-year-old Quentin Fortune, of Somerdale, was at a nearby diner. Investigators say he was dressed only in a T-shirt, boxer-briefs and sneakers and covered in what appeared to be blood.

Fortune is in jail and awaiting a court appearance.

It's unclear if he has an attorney who could comment on the accusations, and the prosecutor's office didn't immediately reply to an email asking whether he has a lawyer.
