“If the killer of Prince Joshua Avitto knows what I know, he will turn himself in,” lifelong Boulevard Houses resident Al G. told the Amsterdam News, surrounded by police and community members searching for a child killer.

The emotional temperature in East New York is close to the boiling point as residents try to make sense of the situation and bring justice to yet another case of a senseless murder of a child. A.T. Mitchell, founder of Brooklyn-based community group Man Up! said, “It is time to call for a city of emergency!”

As of press time, the East New York community and the NYPD were frantically trying to find the suspect believed to have stabbed to death 6-year-old Prince and 18-year-old Tanaya Grant-Copeland and seriously injured 7-year-old Mikayla Capers. All this occurred this past weekend.

Grant-Copeland was found stabbed almost 30 times on Stanley Avenue near Linwood Street in East New York on Friday by a cab driver. She was just blocks away from the area where the killer cornered best friends Prince and Mikayla in an elevator as they went to get icies on Saturday night. It has been reported that the suspect got into the elevator, told the children to be quiet and began stabbing them. Bravely, Mikayla tried to defend the both of them.

The killer got out and ran off through the housing project, leaving the knife, which was recovered by the police. Meanwhile, as her best friend lay dying, Mikayla was able to drag herself out of the elevator on the first floor. But with up to 16 stab wounds and a collapsed lung, she is in critical condition at an area hospital in Manhattan.

Cops are analyzing DNA found on the knife.

“I want to see this guy,” said Al G. “Those children called me Uncle G. Boulevard is a family. There is a code in whatever you do. No children. No women. No elderly. No disabled. I can’t eat, I can’t sleep. Yeah, I want to see this guy. They’ll get him.”

As he continues his routine of walking to his son’s school with his son’s superhero backpack on, Prince’s father, Nicholas Avitto, struggles to come to terms with Prince’s senseless death. He told the Amsterdam News, “We enjoyed walking to school together. That was my job. So I do it now. I know he is not here physically, but I walk and I talk to him like he is still here. It’s what I want to do—for me.”

Walking solemnly down Stanley Avenue, Avitto nodded at and hugged numerous passersby—friends and strangers just wanting to express their condolences.

“I’m hurting,” the devastated father told the AmNews, as he fought back tears. “He took away my buddy. And the thing is, I know that guy. When I saw the picture of him, I said, ‘He used to sleep in the hallway in my building.’ I gave him a quarter or a dollar or a cigarette. But I haven’t seen him in months. People would give him plates of food. I told the police to go to the homeless shelters. He was the last person I would think would do this—but he took my son.”

Police are focusing on homeless shelters; reportedly, there are 10 within a two-mile radius in that East New York area. The NYPD are also looking into men who have been recently released from prison.

Police say the suspect is a heavyset, 6-foot-tall Black man, 25-35 years old. He was last seen running from the scene wearing a grey shirt.

On Wednesday morning, just before a press conference outside the Boulevard Houses (on Stanley Avenue at Schenck Avenue), Brooklyn Borough President Eric L. Adams told the Amsterdam News, “I called people on the ground and asked them what they needed. They said they need posters and flyers. I got them that. Then they said the family was in need of money for the funeral and stuff, so I called Western Beef, and they donated $10,000. Then they asked me what else did they need, and I said, ‘Well, we need to increase the reward money [$1,700],’ so they donated $50,000.”

Joined by Avitto’s parents, as well as the parents of Grant-Copeland, at the press conference, Adams thanked Western Beef on behalf of all Brooklynites and urged parents to be extra cautious with their children. He was accompanied by Mitchell, Benjamin Petrofsky, corporate counsel for Western Beef, and NYPD Assistant Chief Gerald Nelson, commanding officer of Patrol Borough Brooklyn North.

Any evening now, you can see mothers and parents holding their children with a tighter-than-tight grip as they walk through the neighboring streets. You can see them paying their respects to the tremendous memorial site, adorned with flickering candles, mounds of flowers, teddy bears and signs of love, Prince’s baseball cap and even a video game controller. One 9-year-old boy left a yellow candle and cookies. “I just wanted him to have them if he was hungry,” he told the AmNews.

Mitchell told the paper, “We are at breaking point. This was a beautiful, handsome young man, and his murder makes no sense. This violence in our community has to stop.”

Upon hearing the heartbreaking news, Mitchell and his team of peacekeepers took to the streets, as they have for many years, to not only search for the man suspected in the two child killings and attempted murder of another, but also to warn residents that a child killer was in their midsts.

As fear runs through the neighborhood, the concern is that he will kill again. Mitchell said to locals, “Don’t protect this man. Don’t hide him. He is a child killer.”

Meanwhile, Mitchell and his Man Up! violence interrupters are taking children to school, walking them home, “making sure they are safe,” said Mitchell. “It is going to take this community working with the police, but the community has got to be the first responders and nip any of these problems in the bud before they start. We live here. We know what this is.”

Brooklyn District Attorney Ken Thompson told the AmNews, “We will do all that we can to catch this killer.”

As folks have criticized the fact that there are no cameras in the housing development, former City Council Member Charles Barron demanded to know why the New York City Housing Authority (NYCHA) is sitting on $27 million that has been set aside to put cameras in their buildings. “I allocated $500,000 for the [Louis H.] Pink Houses in 2009; the cameras weren’t put in until last year. Why is the city stalling on this?”

In the wake of this tragedy, though, Barron is also working with NYCHA to have the family moved to another location.

Mayor Bill de Blasio and Police Commissioner Bill Bratton did not respond to an AmNews inquiry if either of them had actually met with the family yet.

State Sen. John L. Sampson told the AmNews, “The vicious and senseless stabbing of two little children fills me with revulsion and anger. Such senseless slaughter by a depraved criminal who attacked two innocent and defenseless children is an abomination and an act of unadulterated cowardice. I have one message for this thug: Give yourself up, because we will find you, and you will be prosecuted to the fullest extent of the law.

“I am urging parents in the area to exercise maximum caution to help prevent another bloody rampage by this depraved criminal with a knife. But rest assured, he will be caught.”

At the memorial, streams of moms and dads came to pay their respects. Dorothy Randall, who has lived in Linden Projects for 10 years, said, “My duty everyday is to get out, because these elevators are unsafe. People use the projects to commit crimes and victimize those that can’t get out.”

Toya Jones lives a few blocks away from Prince apartment. She said, “I came here because I wanted to let my girls know how real it is.”
