The Lubbock County Criminal District Attorney's office has charged Ricky Pena III with murder.
Pena called NewsChannel 11 last week and said he shot Joshua Sarate, 40, in self defense. He claimed their argument stemmed from a dispute over money.
Police found Sarate lying in the 500 block of East 36th last Monday, with a gunshot wound to the chest. EMS took him to University Medical Center where he later died.
