NATCHEZ — The third victim of the Feb. 18 brutal attack during a home invasion robbery in Gonzales, in which her husband and son were murdered, died Friday.

Ascension Parish Sheriff’s Office deputies discovered Shirley Ann Marchand, 71, badly injured at her house in Gonzales after the robbery. Her husband, Robert Irwin Marchand, 74, and son, Douglas Dooley Sr., 50, of Tennessee, were found dead.

Marhand was being treated at the Our Lady of the Lake Hospital in Baton Rouge.

A safe containing a $500,000 collection of gold coins is believed to be the reason for the home invasion.

The Advocate in Baton Rouge reported last week that investigators had made progress in attempts to verify a safe found in Livingston Parish on Feb. 20 was the Marchands’ stolen safe and placing the time of attack to 11 p.m. on Feb. 18.

Marchand is the mother of Natchez resident Teresa Godbold.

Services for Marchand will be at 10 a.m. Wednesday at the Church of Jesus Christ of Latter Day Saints on Lower Woodville Road with Bishop Deric Masten officiating.
