Human remains found in the basement of a New York home have been identified as those of a man who went missing in 1961, NBC News reports. The discovery has prompted a homicide investigation, as an autopsy reportedly found that the skull of the man, George Carroll, had been fractured by blunt-force trauma. Carroll’s sons and two grandsons found his bones while excavating the basement of the Lake Grove home previously owned by both their parents, police said. After Carroll vanished six decades ago, police say his wife Dorothy never gave her four children a straight answer on what happened to their father, NBC reports. He was never reported missing, according to authorities in Suffolk County, and Dorothy Carroll's death in 1998 left the family without any answers. Carroll’s son and grandsons reportedly decided to excavate the basement due to long-running rumors in the family that George Carroll was buried there.
