Brandon Lane Clampit, a 50-year-old White man remembered by loved ones as someone who "would give anything he had if you needed it," was killed outside his home in Wichita Falls, Texas, on the evening of June 20, 2024. Police responded to a call about shots fired in the 1500 block of Smith Street shortly after 10 p.m. and found Clampit lying in the street. He had been grilling food just before the incident. Emergency responders transported him to a hospital, but he died from his injuries. His death was recorded as the city's sixth homicide of the year.
The investigation into the shooting quickly uncovered that Clampit had been communicating via his cell phone with an individual to arrange a marijuana transaction. Detectives obtained surveillance footage from the area that showed two people approaching Clampit’s residence around the time of the shooting.
The video captured a muzzle flash from a handgun, and the two individuals were then seen fleeing the scene.
Based on evidence from the phone and surveillance video, police identified two cousins, Marqwon Griffin and M.H. Griffin III, as suspects. After a brief pursuit, officers arrested Marqwon Griffin. On July 12, 2024, the Wichita Falls Police Department’s SWAT team executed a search warrant at a home on Gerald Street, detaining several people for questioning. M.H. Griffin III was among those detained.
Both Marqwon and M.H. Griffin were arrested and charged with capital murder, each held on a $750,000 bond. According to allegations in the arrest warrant, M.H. Griffin told investigators that he and his cousin went to Clampit’s home for the drug deal. He stated that after the transaction was finished, Marqwon pulled out a 9mm handgun and demanded Clampit give him everything he had. When Clampit said he had nothing more, Marqwon allegedly shot him, and the two fled. Marqwon Griffin declined to speak with police and requested a lawyer.
In May 2026, M.H. Griffin III, then 18, pleaded guilty to a reduced charge of manslaughter. As part of the plea agreement, 78th District Court Judge Meredith Kennedy sentenced him to 20 years in prison.
