The Grayson County Sheriff’s Office arrested one man Friday and is searching for a second related to a shooting that occurred during an apparent botched drug deal outside Collinsville on Wednesday.


GCSO investigators executed a search and arrest warrant Friday morning in Collinsville and took Christopher Seth Rich, 20, into custody on an aggravated assault with deadly weapon charge. Rich was also charged with possession of marijuana concentrate between one and four grams.


GCSO Lt. Heath Wester said the investigation also led to an arrest warrant being issued for Austin James Elvington, 18, for aggravated robbery. Wester said Elvington is from the Whitesboro area, though his current whereabouts are unknown. West said Elvington is believed to be armed and considered dangerous.


On Thursday, Wester said investigators believed at least five people met on a county road northwest of Collinsville on Wednesday afternoon in order to sell and purchase marijuana.


“They were in a car and they met outside in the county on Pearce Street,” Wester said. “That’s where the alleged drug transaction was occurring.”


Wester said investigators believe the five people agreed to exchange one pound of marijuana, when gunfire broke out. The lieutenant said one person was shot in the shoulder and was treated and released at Wilson N. Jones Regional Medical Center. Wester said the suspected male shooter and several others with him fled the scene prior to deputies’ arrival.


“There was one shooter, but probably three or four people with him,” Wester said.


On Friday, Wester said GCSO considers the situation an active, ongoing investigation. Those with information regarding the incident or the suspect’s locations are asked to call the Grayson County Sheriff’s Office at 903-813-4408.
