KENDALL, N.Y. — An Orleans County man is now charged in connection with the deaths of the mother and son found dead inside their upstairs apartment in Kendall last month.

The Orleans County Sheriff's Office says 39-year-old David Wiley lived in the other apartment of that Center Road duplex. He's now charged with two counts of criminally negligent homicide and two counts of reckless endangerment in the deaths of Joan Gilman and her 14-year-old son, Richard, "RJ"  Gilman. 

Authorities say Wiley was a tenant and the caretaker of the Center Road duplex that Joan Gilman and her son lived in. They say he was the one who installed and ran a generator for more than 17 hours inside a closed garage right below the Gilman's apartment.

Firefighters found Joan Gilman and her son dead in their bedroom the night of April 18th. From the start of this investigation, authorities believed that the Gilman's died from carbon monoxide poisoning. Autopsies found that both had extremely high levels of carbon monoxide in their systems. Authorities said that National Grid had shut off the power to the home two days before their deaths and that the electrical bills for National Grid were in David Wiley's name.

Undersheriff Christopher Bourke says Wiley engaged in conduct which created a grave risk of death to another person and that he failed to perceive the substantial and unjustifiable risk that would result. 

Friends and neighbors say Joan was a kind and hardworking single mom and that RJ, a freshman at Kendall High School, was adventurous, funny and just a sweet boy.

Wiley was arraigned in the Albion Town Court and is being held on $2,500.
