A teenager in New Jersey was taken into police custody after his parents, sister and a family acquaintance were found dead inside the family’s home late on Sunday. The statement said that it “appears” that the teenager, 16, had used a semiautomatic rifle to kill his father, Steven Kologi, 44; mother, Linda Kologi, 42; sister, Brittany Kologi, 18; and an acquaintance, Mary Schultz, 70. The police went to the home in Long Branch, a seaside New Jersey town of about 30,000 people, after a 911 call reporting a shooting.
