NEW YORK -- Dozens of NYPD officers swarmed an apartment building in the New York City borough of Queens after four people, including a young boy, were shot and killed, CBS New York reports Monday. The station writes that gunfire erupted around 8:30 p.m. local time in Astoria.
CBS New York says the incident appears to be a murder-suicide and that a weapon was recovered.
The Associated Press reports that a 5-year-old boy was among the dead. Along with the boy, two women and a man were found dead in a first-floor apartment. AP says that the man's throat had been slashed, according to New York Police Department Chief of Detectives Dermot Shea.
The station writes that police aren't looking for any additional shooters or suspects.
It's not clear whether the victims were related. Shea cautioned that the investigation is in its early stages.
He said the possibility of a murder-suicide is something they're looking into.
"We don't lean either way, but that is that something, certainly, we will look to," he said.
AP reports that investigators are interviewing the person who dialed 911 and examining data to determine whether police had received any relevant calls in the past from not only the apartment but the nearby area.
"We don't want to leave any stone unturned," Shea said. "There are calls that we believe are going to be related to that building, but it's a little preliminary."
Video posted to Twitter from a CBS New York reporter shows a heavy police response at the scene as bystanders gathered behind police lines.
