An Orleans County man accused of causing the carbon monoxide deaths of a mother and son has pleaded guilty. David Wiley Junior was charged with criminally negligent homicide and reckless endangerment, but in a court hearing Monday night, he took a plea deal. Wiley was the caretaker of the home in Kendall where Joan Gilman and her 14-year-old son Richard lived. In April 2018, he ran a generator in a closed garage under the victims’ bedroom for 17 hours. The power was off due to unpaid bills. Gilman and her son were killed. Wiley will be sentenced July 1.
