A Mississippi woman has been sentenced to life behind bars after admitting she murdered her adult son, concealed his body behind a fabricated wall inside her home, and spent weeks deceiving relatives and investigators by pretending he was still alive.
Jerri Roby, 69, received the life sentence on Thursday after pleading guilty to the first-degree murder of her 42-year-old son, John Allen Gaither, whose disappearance sparked a months-long investigation in Gulfport.
Missing Person Investigation Raised Early Suspicion
The investigation began in December 2023 after Gaither’s brother contacted Gulfport police to report that he had not heard from him for about a week.
Roby, who shared the home with her son, initially claimed that Gaither had traveled to Louisiana using an Uber to purchase a vehicle.
However, investigators found no evidence of such a trip after reviewing his ride-share account, prompting further concerns about her version of events.
Family Doubts Messages Sent From Victim’s Phone
Weeks after Gaither was reported missing, his stepmother and brother again contacted authorities after receiving text messages and a phone call from his number.
Although the communications suggested Gaither was alive, his relatives immediately became suspicious, insisting that the messages did not sound like him.
Their concerns encouraged investigators to continue pursuing the case.
Fake Wall Concealed Grim Discovery
Armed with a search warrant, investigators entered Roby’s Gulfport home on January 18, 2024.
During the search, they uncovered a false wall constructed in the front section of the residence.
Behind it, officers discovered a large box containing Gaither’s remains.
A medical examination later confirmed that he had died from a gunshot wound to the back of the head.
Court Hears Mother’s Explanation
During court proceedings, Roby admitted she shot her son in what she described as a “spur of the moment” decision.
She also claimed she believed she was ending his suffering because he had been struggling with depression, telling the court she had “put him out of his misery.”
Purchases Before Disappearance Drew Investigators’ Attention
Evidence presented during the investigation revealed that Roby had made several unusual purchases shortly before Gaither was reported missing.
Records from a Gulfport Home Depot showed she bought 15 bags of sand, patch-and-seal tape, straw, and a large dumpster bag roughly one week before the missing person report was filed.
Investigators also found receipts from earlier purchases that included plastic sheeting, soil and additional tape, items prosecutors argued were used to help conceal the crime.
Authorities Uncovered Elaborate Deception
Investigators said Roby went to considerable lengths to convince family members that Gaither was alive.
His stepmother, who lives in California, told police she received a letter supposedly written by Gaither claiming he had traveled to the Philippines to meet a woman.
Assistant District Attorney Matthew D. Burrell told the court that Roby admitted forging those letters.
Prosecutors also said she sent text messages while impersonating her son and persuaded her boyfriend to call relatives while pretending to be Gaither.
Previous Conviction Emerged During Investigation
Authorities also revealed that Roby had previously been convicted of murder in Florida in 1995.
Investigators further discovered that she had used multiple aliases over the years.
Following the discovery of Gaither’s body, Roby was taken into custody after being released from the hospital, where she had been treated after swallowing pharmaceutical pills while officers were removing her from the home.
Prosecutors Say Sentence Brings Accountability
Following the sentencing, District Attorney Crosby Parker said the guilty plea and life sentence represent an important step toward justice for Gaither’s family.
Parker praised investigators for remaining committed to the case despite what he described as Roby’s extensive efforts to mislead authorities and distance herself from the killing.
He said the outcome provides accountability for a crime that deeply affected the victim’s loved ones and the wider community.
