A 1-year-old boy died on Sunday night after being shot in the head on a Brooklyn street, the police said.

The shooting occurred on the corner of Livonia Avenue and Bristol Street in the Marcus Garvey Village project in Brownsville about 7 p.m. The boy, Antiq Hennis, was hit in the left side of the head and pronounced dead at Brookdale University Hospital and Medical Center.

According to the police, Antiq was with his parents and in a stroller when he was shot as the family crossed Livonia Avenue . It was not clear who was the target of the gunman, the police said.

Antiq lived on Riverdale Avenue, a few blocks from where he was killed.

Gina Gamboa, 22, who had been visiting her boyfriend, said she heard three gunshots, and saw one man running away and another standing near a stroller.

The man standing by the stroller began to run, too, Ms. Gamboa said, but came back for the child. “The baby’s head was to the side,” she said. The stroller, she added, was covered in blood.

Moments later, residents began to emerge from their homes and cries of “a baby got shot” could be heard. “For stupid stuff people want to kill someone,” Ms. Gamboa said.

Officers shut down streets around the site of the shooting, and residents returning to the block were initially not allowed to enter their homes.

Outside the hospital, a woman who said she was Antiq’s godmother was doubled over in grief. “Oh, God, he’s so innocent,” she said, adding that she had kissed him goodbye. At a gathering at the family’s home late Sunday night, relatives and friends declined to speak to reporters.

No one else was hurt in the shooting and no arrests were reported by late Sunday night.

Late last month, a 3-year-old boy was shot and critically wounded in his apartment in Ditmas Park, Brooklyn. Investigators later determined that the bullet had been fired inside the apartment. A 22-year-old man was charged with assault, criminal possession of a weapon, endangering the welfare of a child and tampering with evidence, the police said.
