UTICA, N.Y. -- The mugshots of the two people killed after an alleged attempted robbery in Deerfield have been released — meaning they both had a criminal history. Authorities are also investigating if the intruders had been in the house prior to Tuesday afternoon.

The incident on Walker Road turned deadly after the homeowner, 64-year-old Ronald Stolarczyk, shot and killed Patricia Anne Talerico, 57, and her nephew Nicholas Talerico, 27, after they entered his home.

Police found items belonging to Stolarczyk in another home Tuesday night. Oneida County District Attorney Scott McNamara says police are trying to determine if the two robbed Stolarczyk's home about a week ago.

"A truckload of evidence was seized last night. At this point, we have to determine whether or not that was evidence that had been taken from this residence on a prior occasion," McNamara said.

The Oneida County Sheriff's Office released past booking photos of Patricia and Nicholas, saying that both have criminal records.

Patricia Talerico had been arrested more than 20 times in the past, and Nicholas Talerico was arrested on more than one occasion.

Both suspects were Utica residents, although they lived at different addresses.

Stolarczyk is facing charges for using his deceased father's gun to kill the two, which he never registered to himself. He is currently being held at the Oneida County Jail.
