The mother and two sons of a murdered Amarillo physician have filed a wrongful death lawsuit against Doctor Thomas M. Dixon, age 48, as well as another man named David N. Shepard.
Doctor Joseph Sonnier, the chief pathologist for Covenant Medical System, was found stabbed and shot on July 12, 2012 in his Lubbock home. Homicide investigators believe that Dixon, a cosmetic surgeon, who operated a plastic surgery clinic in Lubbock, paid David Shepard $9,000 in silver bullion to kill Doctor Sonnier.
Lubbock County District Attorney Matt Powell has reported that detectives found evidence that Dixon hired David Shepard as a hit-man because he was jealous that Doctor Sonnier, age 57, was romantically involved with his former girlfriend.
Both Shepard and Dixon, MD have been in jail since they were arrested in July.
They are each held on a $10,000,000 bond.
