They are Dr. Thomas Michael Dixon, 48, and David Neal Shepard, 51.
According to the website, www.amarillobeauty.com, Dr. Dixon is a plastic surgeon in Amarillo.
The same website indicates he graduated from Texas Tech University.
Both men are in custody in Amarillo.
Arrest warrants issued for both men show Sonnier was both shot and stabbed inside his Central Lubbock home.
According to that warrant, Lubbock Police interviewed Sonnier's girlfriend on July 11th-- the day Sonnier's body was discovered.
She told police her ex-boyfriend was Dr. Thomas Michael Dixon and that he would not leave her alone, even though she was dating Sonnier.
Those warrants show a female witness told police she was with Dr. Dixon in Amarillo the day before Sonnier's body was found and that Dixon had met with a man named "Dave" that night.
Several days after the murder, Amarillo Police were notified by a pawn shop that David Shepard had sold a 100 ounce bar of silver for $2,750.
Police say they interviewed Shepard's roommate, who told detectives Shepard tried to commit suicide in the days following Sonnier's murder by cutting his wrists and that Dr. Dixon had "sewn up" Shepard after the suicide attempt.
Shepard, himself, later told police that he had been watching Sonnier for several weeks.
He said he shot Sonnier several times after coming in through a window.
Shepard said he killed Sonnier because of a "triangle" between a girl, Sonnier and Dixon.
He said Dixon was to pay him three silver bars worth $3,000 a piece to carry out the murder.
Both Dixon and Shepard are being held on $10,000,000 bond a piece.
