FAR ROCKAWAY, Queens — Police on Sunday released new video of a suspect wanted for opening fire on a house in Queens, killing a 10-year-old boy and wounding a man Saturday night.

Justin Wallace and a 29-year-old man, who police identified as a relative of the boy, had just entered a residence when someone fired rounds at them, according to the NYPD.

The shooting took place around 9:30 p.m. on Beach 45th Street in Far Rockaway.

Police initially said the shots came from inside, however, the surveillance video shows the suspect walked up to the house and opened fire, squeezing off eight rapid-fire shots.

Responding officers found Justin unresponsive with a gunshot wound to his torso, police said. The boy was taken to a hospital, where he was pronounced dead, according to the NYPD.

Justin was just days away from his 11th birthday, his family told PIX11 on Sunday.

The adult victim was shot in the shoulder and was taken to a hospital in stable condition, police said.

Investigators believe there may have been a dispute earlier in the evening that led to the shooting.

No arrests had been made, as of Sunday afternoon.

Mayor Bill de Blasio took to Twitter to offer his condolences to Justin’s family and vowed the killer would be brought to justice.

“Justin Wallace should be alive right now. He’s dead because of a coward’s act. He had his entire life ahead of him. It’s a profound injustice. His killer will be brought to justice,” the mayor said. “To his (Justin’s) family: your city shares your anger, it shares your sadness. We mourn with you.”
