A Fulton County grand jury handed up an indictment Thursday against the Ephratah man accused of killing his mother with a .22-caliber rifle in July.
Dibble, 29, faces five charges including second-degree murder. Dibble was arrested shortly after his 57-year-old mother, Gwenda Lisman, was found dead July 1 in her Mud Road home.
A concerned neighbor called authorities when she couldn’t see or hear Lisman. An autopsy since confirmed she died of a gunshot wound to the head.
Dibble, who lived with Lisman at the time, was considered a person of interest right away and further investigation revealed an extensive criminal record and tumultuous relationship with his mother.
Authorities believe an argument got out of hand some time before the morning of July 1, prompting Dibble to shoot his mother with a rifle she had borrowed from a neighbor.
According to a statement from Fulton County District Attorney Louise Sira, Dibble could spend the rest of his life in prison if convicted.
“The maximum penalty for the charge … is 25 years to life in state prison,” she said. “The investigation has been thoroughly conducted and I have every confidence that justice will prevail.”
Lisman’s sister Denise Barrett was also quoted in the release saying the family is relieved that the case is progressing.
“We will never forget my sister,” she said, going on to thank the Sheriff’s Department and family friends for support.
Barrett could not be reached for further comment on the case.
Dibble was also indicted on charges of third-degree criminal possession of a weapon — the rifle — and three counts of criminal possession of stolen property.
Following the shooting, investigators found Dibble had stolen and pawned more than $1,000 worth of his mother’s jewelry.
They also found he had stolen more than $1,000 in NASCAR collectibles and a Husqvarna chain saw from another victim, pawning the collectibles and selling the chain saw to an acquaintance.
Dibble will be represented by Gloversville Attorney Robert Abdella, who could not be reached for comment Thursday.
The District Attorney’s Office said Thursday that Dibble’s arraignment date has yet to be set. He has been in custody since the initial arrest.
