Elizabeth Lackey, 85, Frank Lackey, 89, Elizabeth Krause, 60, and Mae Parker, 68, were found dead inside the Lackeys' Common Street residence on September 8, 2017, according to the District Attorney’s office. The office said at the time that three bodies were found inside and one outside.
According to the District Attorney’s office, Orion Krause traveled to Boston from Rockport, Maine, on September 7. The next day, he and his mother met in Boston and went to his grandparents' home in Groton, Massachusetts. Orion reportedly killed them using a baseball bat, then fled to a neighbor’s home where he was arrested.
According to Mass Live, Orion was found naked in a backyard and had "thin cuts" on his body. Orion reportedly told officers he "murdered four people" and said, "I killed my family with a baseball bat."
When officers went the Lackeys' residence, they reportedly noted the victims "appeared to have severe trauma to the face and forehead," Mass Live reports. The television was reportedly still on in the kitchen.
