Dr. Blake G. Sinclair was a 59-year-old dentist who died after a violent attack at Affordable Dentures & Implants in Tyler, Texas, on March 16, 2022. He and a colleague, 75-year-old Dr. Jack E. Burroughs, were treating a patient, 41-year-old Steven Alexander Smith, when a dispute over the denture procedure escalated into physical violence.

He left briefly, returned, forced his way back into the office, and in the struggle produced a handgun and fired multiple shots. Both dentists were critically injured and later pronounced dead at a local hospital. A nurse at the clinic witnessed the shooting and reported what she saw to authorities.

If anyone was connected to the clinic that day or has additional information about the confrontation before Smith returned to the office, please share what is known.
