The neighbor recalled hearing the shots on Saturday afternoon (in a Facebook post at 1:00 a.m. on Sunday):
In an interview, a [neighbor] said she and her husband were in their backyard when they heard four separate rounds of shotgun fire coming from the general direction of the DiNardo property.
[The neighbor] said she has heard the occasional gunfire from hunters in the area over the years. But this was different, she said
"It was extremely disturbing gunshot fire," she said, estimating that she heard as many as a dozen gunshots in the first round of fire. "It was violent. This person was going bananas."
[The neighbor's husband] said he was sure that they had heard the firing of a shotgun. "I’m familiar with a pistol, a rifle. And shotguns, they’re a blast," he said. "We're pretty dang sure that what we heard is what we heard," his wife added.
All in all, they said they heard four sets of gunfire in a span of about 15 minutes.
[The neighbor] described the shots heard by the couple on Facebook around 1 a.m. Sunday. In a separate comment on the social media site, and while speaking about it on Tuesday, she said she feels guilty for not calling police immediately on Saturday afternoon.
