A 16-year-old boy gunned down his parents and a family friend minutes before the clock struck midnight on New Year’s Eve, authorities in New Jersey said.
His father Steven Kologi, 44, mother Linda Kologi, 42, sister, Brittany Kologi, 18, all "appear" to have been killed with a semi-automatic rifle, the Monmouth Country Prosecutor said in a statement. Mary Schultz, 70, was also shot dead.
The 16-year-old, who has not been named, has been arrested on suspicion of murder.
The suspect's brother and a grandfather were safe following the shooting, the prosecutor said, adding that the teenager was taken into custody without incident,
Over $18,000 (£13,300) had been raised at the time of publication, to pay for the funeral costs for the family.
Brian Yunker, who described himself as a “close family friend” set up the GoFundMe page.
“Linda, Steven, and Brittany were all beautiful people with the kindest hearts you could imagine,” he wrote.
