Overview

• Marshall Garrett, 38, is in police custody, charged with three counts of felony criminal negligence after his dogs fatally mauled 65-year-old Harriette Phillips on March 23, 2025.
• The attack occurred when Garrett's dogs broke through a fence into Phillips' yard, where she attempted to defend herself with a hammer before succumbing to the attack.
• Surveillance footage and witness accounts confirmed the dogs' aggressive behavior and a history of escaping their enclosure, contributing to neighborhood safety concerns.
• Garrett is also facing a murder charge for the October 2024 death of Alton Martin, who died from blunt-force trauma after an altercation involving Garrett and another individual.
• All three dogs involved in the attack were euthanized under Texas law, and Garrett's legal proceedings for both cases are now underway.
