NEW ORLEANS -- A man accused of stabbing two people, one fatally, with a bayonet faces life in prison after being indicted by an Orleans Parish grand jury.

Kelvin Boykins, 49, is accused of stabbing a man in the forearm during an armed robbery on Aug. 24, then fatally stabbing a man outside the Manchu Food Store on North Claiborne Avenue on Aug. 28.

On Aug. 24, a 57-year-old man told police that he intervened when Boykins threatened to rob a woman outside the Cajun Seafood grocery at 1479 N. Claiborne Avenue. According to the DA's office, Boykins pulled a bayonet from his waistband and stabbed the man in his left forearm before fleeing on a bicycle.

Four days later, Boykins allegedly stabbed Ronald Pitts outside the Manchu food store at 1413 N. Claiborne Avenue. Police say Pitts stole a six-pack of beer from the store and was fleeing when Boykins stabbed him in the chest, killing him. Boykins was arrested soon after.

Boykins faces a mandatory life sentence if found guilty of murdering Pitts. He is currently being held on a $310,000 bond.
