A 22-year-old Brooklyn man was charged Tuesday with the shooting death of a St. John’s University graduate during the J’Ouvert celebrations on Monday.

Regenald Moise, of Westminister Road, was taken into custody in the morning and questioned about the fatal shooting of Tiarah Poyau, 22. Hours later, detectives charged him with second-degree murder, criminal possession of a weapon and reckless endangerment.

Poyau was shot in the face, police said.

Tyreke Borel, 17, was also killed in a separate shooting at J’Ouvert.

Poyau was shot on Empire Boulevard at about the time police were responding to a report of a fight in the vicinity of Washington Avenue and McKeever Place.

No suspect has been identified in the Borel shooting.

The two killings occurred despite what Mayor Bill de Blasio called “extraordinary” measures to protect revelers attending the annual celebration of Caribbean culture.

De Blasio said Monday that the city will review what action to take with regard to the future of J’Ouvert and the West Indian Day parade. He said the city will consider “all options,” hinting that banning J’Ouvert would be a possibility.

An estimated crowd of 250,000 people attended the J’Ouvert festivities last weekend.
