Felix Edil Rodriguez told a "cooperating witness" that he shot and killed Alejandro Dominguez-Hernandez during a drug deal, according to documents filed in Fayette District Court.
The cooperating witness — apparently a Kentucky State Police undercover informant — recorded the conversation, the documents say.
Rodriguez, 20, is charged with murder in the death of Dominguez-Hernandez, 23, who was found Monday night in the back seat of a car parked on Johnston Road. He was pronounced dead at the scene.
Lexington police announced Rodriguez's arrest on Wednesday.
A lawyer for Rodriguez entered a not-guilty plea Thursday afternoon during an arraignment in court. Rodriguez was being held in the Fayette County jail on $500,000 bail. He's scheduled to be back in court Feb. 4 for a preliminary hearing.
According to an affidavit filed in the case, state police told Lexington officers that the cooperating witness had met with Rodriguez and that Rodriguez had admitted shooting the victim during that conversation.
The document says Rodriguez described a plan to buy cocaine from Dominguez-Hernandez and kill him.
According to the account in the affidavit, the victim arrived at Johnston Road, a rural road near Bryan Station Road, and got into the back seat of a car to complete the drug transaction.
At that point, the affidavit says, Rodriguez ran out from behind a barn and fired a number of shots into the car, killing Dominguez-Hernandez.
The victim suffered multiple gunshot wounds, according to the Fayette County coroner's office.
