SOUNDVIEW, Bronx — A 31-year-old woman stabbed a 70-year-old man to death Friday at a supermarket in the Bronx, according to police.

Police say the incident happened shortly before 1 p.m. near Westchester and Commonwealth avenues in the Soundview section of the Bronx.

Witnesses inside said the woman, who police identified as Madelyn Tamarez, was mouthing off and yelling at the victim, accusing him of being racist.

Friends of the victim tell us he was an Army veteran and lived in a Vets home around the corner from the store for 17 years. He reportedly has no family in the New York City area.

"He was a good guy. I know him long time. He would come to the store every day and relax, drink coffee, talk," said Sam Aden, whose father owns the store.

Witnesses say Tamarez left the store and returned approximately 15 minutes later, armed with a knife.

"She fight him hand-to-hand. She grabbed a knife from somewhere else. She stabbed him two times and he died," Aden said.

The man suffered a stab wound to his torso and was rushed to NYC Health + Hospitals/Jacobi where he was pronounced deceased. His identity is being withheld pending family notification.

Tamarez tried to run off but police arrested her at the scene.

She has been charged with murder, manslaughter and criminal possession of a weapon, police said Friday night.

It was not immediately clear if the two were known to each other.
