Trinity Rodriguez fled the parking lot of Fairlawn Industries, leaving the victim behind, but was nabbed by borough police a few blocks away, they said.
The victim, 27, from Garfield, held a gauze pad to his bleeding arm while talking with responding officers on the other side of Maple Avenue from the Craftsman restaurant around 7:45 p.m. May 18.
He eventually got into a Fair Lawn ambulance and was taken to Hackensack University Medical Center, where Fair Lawn Police Sgt. Eric Eleshewich said he needed 13 stitches to close the gash.
Rodriguez was with her young son when police took her into custody a few blocks away.
A police officer talked with the boy, who was in the back seat of her Volkswagen Passat, getting him to smile and laugh, during the 7:45 p.m. stop (see photo at top).
The youngster eventually was secured in a car seat and brought to police headquarters to be reunited with his father.
Rodriguez told police that she'd tossed the knife out the window, responders at the scene said. Following what became a futile search, they discovered the knife in the trunk.
She remained held in the Bergen County Jail on Friday, May 19, charged with aggravated assault and illegal weapons possession.
Police didn't disclose the source of the conflict.
Citywide Towing impounded the Passat.
