MILTON - An investigation into the deaths of a mother and son that occurred two weeks apart has shown both individuals died of natural causes.
Northumberland County Coroner James Kelley reported Wednesday the investigation into the deaths of Vennie Boyles, 80, and her son Mark Boyles, was completed following toxicology tests and autopsies conducted in November.
Vennie Boyles, of 8 Park Lane, the same address as her son, was found dead in her home's bathroom shower Nov. 4. Mark Boyles was sought as a person of interest and questioned five days after her death. He was found dead in his vehicle in a parking lot behind Kuhns Brothers Surplus Outlet in Milton Nov. 19.
Following the Nov. 6 autopsy conducted by Dr. Samuel Land on the mother, Kelley said the cause of death was due to atherosclerotic cardiovascular disease and the manner of death is natural.
The coroner said there was significant trauma to the back of her head and her right hand, but the injuries were not lethal.
The autopsy on her son was conducted Nov. 21 by Dr. Rameen Starling-Roney. Kelley reported the cause of death was due to cardiomegaly, an enlarged heart with a contributory factor of atherosclerotic cardiovascular disease, and the manner of death was natural.
