The 7-year-old girl savagely stabbed in a knife attack that left her playmate dead walked out of a hospital Wednesday as a New York miracle.  Mikayla Capers was stabbed June 1 inside an elevator at the Boulevard Houses in East New York, Brooklyn. She was initially listed in critical condition, but began walking on her own last week.  Her great-grandmother, Regenia Trevathan, said that despite the arrest of Daniel St. Hubert, the family was still concerned about her safety.  “Listen, she was stabbed 16 times,” Trevathan said Wednesday night. “She’s a witness with protective custody.” The girl’s relatives hoped to be in a new apartment by the end of the month.  Daniel St. Hubert, who allegedly stabbed to death P.J. Avitto, 6, tried to speak as he was indicted Wednesday in Brooklyn Criminal Court.  Daniel St. Hubert, who allegedly stabbed to death P.J.

Avitto, 6, tried to speak as he was indicted Wednesday in Brooklyn Criminal Court.  Mayor de Blasio said earlier that the city would help Mikayla adjust. Her pal Prince Joshua (P.J.) Avitto, 6, was killed in the elevator attack.  “She misses her dear friend P.J., but her life is a testimony of perseverance and strength, and we’re going to be here for her,” de Blasio said at a news conference at Boulevard Houses to announce the belated installation of surveillance cameras there and at 48 other NYCHA buildings.  The City Council had set aside $27 million in July for security cameras in NYCHA facilities — but the work never happened. De Blasio admitted red tape from both his and the prior administration stalled the project.  No cameras were in place when St. Hubert, 27, allegedly stabbed P.J. and Mikayla. St. Hubert, a hulking ex-con with a history of mental illness, tried to speak in Brooklyn Criminal Court Wednesday but was denied.  “Is it all right I have a moment with the court, a short moment?” St. Hubert inquired after a prosecutor announced he’d been indicted in P.J.’s murder.  “No,” Judge Matthew Sciarrino replied flatly. Shackled and wearing an orange jail-issued jumpsuit, St. Hubert was escorted to Bellevue Hospital.  “I guess he wanted to play a crazy, mental role. I don’t know,” said P.J.’s father, Nicholas Avitto.  St. Hubert faces 50 years to life in prison if convicted. Police are also investigating whether he fatally stabbed 18-year-old Long Island University nursing student Tanaya Copeland on May 30. She was killed just four blocks away from where the children were attacked.  Copeland, dressed in her band uniform, got an emotional sendoff Wednesday at Bethlehem Baptist Church in East New York.  Her heartbroken mother, Rochelle, stood next to Tanaya’s white coffin, hugging attendees.  “She was loved. You can tell from the turnout that she was loved. She was a special child,” said the mom, who was overheard saying she was “good, but tired.”  Police said St. Hubert is also a suspect in the June 4 stabbing of Kyle Moore, a 53-year-old homeless man. He was in critical condition at Bellevue. St. Hubert hasn’t been charged in the attacks on Copeland or Moore.  With Jennifer Fermino, Edgar Sandoval and Terence Cullen
