The party was being held at 87-19 90th Street – an abandoned home - when the crashers entered uninvited and began to raise a ruckus.
After they left the property, a few houses down on 90th Street, the party crashers encountered Callao and accused him of being gay.
The gang of teens surrounded Callao, and then beat him over the head with what is alleged to be a metal pipe that was picked up off the ground.
Four teens, Alex Velez, 16, of the Bronx, Christopher Lozado, 16, Nolis Ogando, 17 and Luis Tabales, 16, all of Queens, were arrested on charges of gang assault and criminal possession of a weapon.
One resident who did not want to be named for fear of retaliation said that the commotion woke him up and when he went outside, he saw Callao on the ground surrounded with blood as the cops and EMTs arrived.
The event is not the first of its kind in Woodhaven. The neighborhood has dealt with its share of violence within the past year.
“The neighborhood is not as quiet as it used to be,” the resident said. “In the past five years the neighborhood has changed and not for the better.”
The Woodhaven Residents Block Association had recently addressed the issue of abandoned houses in the neighborhood at one of their meetings.
“That house was not boarded up. Why?” the resident said. “Maybe now the city will start to do something about it.”
City Councilman Eric Ulrich condemned the attack and sent his prayers out to Callao's family and friends. “I was truly saddened to hear about it,” he said in a statement. “Our streets will not be safe until the individuals who are responsible for this heinous crime are brought to justice. Senseless acts of violence such as this will simply not be tolerated.”
Callao, who had just graduated from high school, was taken to Jamaica hospital in critical condition and on life support. He died on Monday.
Police are urging anyone who witnessed the attack or who has any information about the perpetrators to come forward by calling the authorities or the anonymous tip line at 1-800-577-TIPS.
