Investigators are now looking into known associates of Eberly who have not been seen in a while — including a woman he reportedly lived with.
"This is obviously troublesome," said Trenton Chief of Police Todd Scheffler, per Detroit News. "We've got some suspicions. We're looking into some people he knew, who maybe haven't been heard from in a while."
Steven Voss, director of police and fire services added: "He lived there with a female, and we're trying to locate her."
According to the News Herald, before his death, Eberly previously had brushes with local police, but no felonies.
Following the death of his parents, he sold the home and made his way to Tennessee.
