Baylor Gibson III told the Herald Sun, his brother, Eric Gibson “had some psychiatric issues.”
Neighbors said the house has been on the market for more than a year.
County records indicate Margaret Gibson bought the property in 2001 and built the house a year later.
“She did a marvelous job at the front yard. All of the trees and shrubs you can see and the stonework has been done by her. She was very meticulous about it,” said Cotton, who added she was often spotted with her gardening gear.
The house is located on Deming Road off of East Franklin Street and is valued at more than $640,000 on local real estate websites.
Margaret Gibson's late husband of 62 years, Baylor Gibson Jr., also lived in the house until his passing in 2012. He was a retired U.S. Marine Corps Colonel, and they had five sons together.
“She was just extremely friendly, always happy, always in a good mood,” Cotton said.
Margaret Gibson walked energetically every morning around the neighborhood and up the steep hill, Susan Outterson, a neighbor of the Gibson's said.
She sang in the choir of St. Thomas More Catholic Church, where a Christian burial mass will be held. The family has not announced a date. She will be interred with her husband at Arlington National Cemetery.
