NEW YORK (CBSNewYork) – Police have arrested a woman accused of stabbing a 70-year-old man to death inside of a Bronx deli Friday afternoon.

According to authorities, the victim was inside a store on Westchester Avenue when he got into a verbal argument with 31-year-old Madelyn Tamarez around 12:20 p.m.

Police sources tell CBS2 that Tamarez left the store, came back with a knife, and then stabbed the victim three times in the chest.

Witnesses say the victim was a longtime customer of the bodega who was purchasing coffee when the woman, who they say appeared to be intoxicated, started fighting with him and calling him racist.

Employees at the store say Tamarez has a reputation in the neighborhood for acting belligerently, but they have no idea why she’d take her anger out at the elderly victim.

“She stabbed him two times in his heart,” store worker Sam Alahadie said.

Tamarez can be seen on surveillance video backing out of the store waving her knife before walking away. Moments later, the victim stumbled out holding his arm and fell to the ground.

The victim was rushed to NYC Health+Hospital/Jacobi, where he was pronounced dead. Sources say police arrested Tamarez as she was trying to run from the scene.

Police didn’t immediately release the victim’s name, pending family notification.
