Powder Springs, Georgia – Authorities say a 31-year-old man executed his mother and stepfather inside their home after they returned from a birthday celebration, telling investigators he was simply “tired of them and wanted to be alone.” The violent incident has left a close-knit community stunned, with neighbors describing the couple as warm, generous people who had recently allowed their adult son to move back in.
What Investigators Say Happened
Police say the shooting unfolded late on December 6 at a residence in Cobb County. According to the arrest warrant, Martin Duberry admitted firing multiple shots at his mother, 72-year-old Monica Brookins, and his stepfather, 73-year-old John Wells, shortly after they arrived home. The couple had been out celebrating Wells’ birthday earlier that evening.
Authorities allege that Duberry told them he was overwhelmed and frustrated living with his parents.
“He was tired of them and just wanted to be alone,” investigators wrote in the arrest warrant.
Police say he also stated he did not remember how many times he fired after the initial shots to their heads.
The 911 Call and Police Response
Officials confirm that Duberry called 911 himself moments after the shooting. Powder Springs officers arrived to find him at the home with his hands raised, while Brookins and Wells were found critically wounded inside. Both victims were transported to a hospital, where they were pronounced dead from multiple gunshot wounds. Investigators later confirmed that Brookins was shot five times, and Wells was shot three times.
A neighbor described seeing officers approach the home with weapons drawn.
“I just looked out my window, and I saw a man coming out his house with his hands up,” said resident Sanaa Pygatt.
Charges Filed Against Duberry
Duberry is now facing two counts of felony murder, along with eight counts of aggravated battery and possession of a firearm during the commission of a crime. Powder Springs Police characterized the case as an “isolated domestic situation,” noting there is no threat to the public.
Neighbors Say the Couple Recently Opened Their Home to Him
Friends and neighbors say Brookins and Wells had allowed Duberry to move back in, describing the pair as kind and welcoming community members. The news of their deaths has devastated those who knew them.
Neighbor Kay Hughes expressed disbelief at the motive alleged in the arrest warrant.
“Why would somebody shoot two people that was letting you live in their house?” she said. “They was just good people.”
Another neighbor recalled the couple’s gentle presence.
“They was always super nice,” Hughes added. “Always waving to you, always saying hi to you.”
Community Shock and Domestic Violence Concerns
Local residents say the tragedy has forced them to reflect on the quiet realities of domestic tension and unchecked emotional distress. Incidents involving adult children moving back in with aging parents are becoming more common nationwide, and experts note that unresolved conflict can escalate dangerously when firearms are accessible.
Authorities in Cobb County urge families to seek help if household conflicts intensify, emphasizing that early intervention can prevent violence.
Final Thoughts
The investigation into the December 6 double homicide remains ongoing as authorities prepare for court proceedings. Community members continue to mourn the loss of two longtime neighbors described as generous, friendly, and deeply loved.
