Police identified the man on Wednesday as 79-year-old Isidore Ellin, of Tower Rd., in Middlebury.
According to the Office of the Chief State’s Medical Examiner, Ellin died of blunt force trauma to the head and his death was ruled a homicide.
On Wednesday, police arrested 44-year-old Steven Brockett of Waterbury and charged him with murder, first-degree robbery and first-degree assault of an elderly person.
Brockett allegedly hit Ellin on the head with a weapon.
Police said the victim was targeted and was known by the suspect. There is no threat to the community.
"It's was a targeted incident. It was an isolated incident. It wasn't a random act," said Middlebury Police Chief James Viadero.
Police did not say how the two knew each other or if there was an argument before, but authorities said Brockett stole an undisclosed amount of money from Ellin.
Brockett was arrested on Wednesday evening and is being held on a $750,000 bond. He is expected to appear in court on Thursday.
Neighbors said Tower Road is a quiet street and they were surprised to see police in the area.
"I was shocked. I can't believe it. You just don't hear about that sort of thing in Middlebury," said Susan McGrath.
Police said there hasn't been a homicide in Middlebury in over 20 years.
Anyone with information should contact Connecticut State Police Major Crime Squad at Troop A at (203) 267-2200, or the Middlebury Police Department at (203) 577-4028.
The family of Ellin said in a statement "The family is grieving and making funeral arrangements. (They) want to express their appreciation to local and state police for all they are doing to solve this crime."
