NEW YORK (CBSNewYork) — A Queens man has been arrested in the deadly shooting of 10-year-old Justin Wallace.

Three days after Wallace was shot at a relative’s home, police believe they’ve found the gunman — 29-year-old Jovan Young.

CBS2 was told Young turned himself in to the 101 Precinct on Tuesday evening. He was walked out in handcuffs around 10 p.m.

Young is charged with murder in Wallace’s death and attempted murder in the shooting of Wallace’s 29-year-old cousin.

Police said they knew who they were looking for after they tracked him down using the car and gun from the shooting.

“When someone does something wrong, at least we need to know and feel that there will be real consequences. And in very, very short order, the NYPD found the person who pulled the trigger,” Mayor Bill de Blasio said. “So the message is clear. If you use a gun in New York City, you will be arrested. If you harm someone, if you kill someone, there will be consequences.”

“If you do something like this, you will be found, and you will pay the price for what you’ve done,” he added.

As CBS2’s Jessica Layton reported, police said surveillance video shows Young firing several rounds into a home on Beach 45th Street on Saturday night.

Wallace was struck in the stomach and died a short time later.

“Laying down, curled up … All I could hear from my son, one at a time, [gasping] then I said, ‘Oh my god.’ Then I started to tap him. I said, ‘Wake up, don’t sleep’ … He’s not supposed to die. He’s too young for that,” Wallace’s father told CBS2 on Sunday.

Young’s arrest comes on what would have been Wallace’s 11th birthday.

Meanwhile, the entire community is still in mourning.

“How can anybody that lives around here not be sad or angry?” neighbor Kristal Middleton said Monday.

Some neighbors found the courage to clean the blood stains off the steps.

“To know that their loved one’s blood is still on the steps, I know they don’t have the strength to clean it up,” Middleton added.

Young has one prior arrest from two years ago.
