Mary E. Buckley was 77 and last seen in St. Peters, Missouri, on April 13, 2015. She suffered from Alzheimer’s disease, chronic obstructive pulmonary disease, used bottled oxygen continuously, had very limited mobility, and rarely left home. At the time she lived with her 51-year-old son, Gary Buckley, who was her primary caregiver and held medical power of attorney. Mary was described as a white woman with brown hair and blue eyes, between about 5 feet and 5 feet 3 inches tall, 90 to 130 pounds, missing all front teeth and expected to wear dentures that were reportedly left behind.

On April 21, 2015 hikers found Gary Buckley deceased, hanging from a tree at Eco Park in St. Charles; authorities determined he died by suicide. When police went to the home to notify Mary, she was missing. Mary’s silver 2004 Hyundai Santa Fe was later found deliberately hidden in a wooded area south of the Highway 370 bridge near a train trestle on the east side of the Missouri River.

Does anyone have information about Mary’s movements around April 13, 2015, or recall seeing her vehicle near Highway 370 or along the Missouri River?
