Shanice Robinson’s husband did that, and police said the 21-year-old Port Richmond woman grabbed a kitchen knife and just kept swinging, according to the Staten Island Advance.

Her husband Jamel arrived with his girlfriend a little after midnight Wednesday to get some clothes. Police said Shanice managed to stab his hand and stomach. The girlfriend’s hand was also sliced when she tried to intervene, the Advance said.

Mrs. Robinson is charged with two counts of second-degree assault, second-degree menacing and second-degree harassment, and a single count of fourth-degree criminal possession of a weapon, officials told the Advance.
