Prosecutors said there was little evidence to suggest a motive for the killing, but no doubt that Ochoa and his co-defendant, Osbaldo Torres, 37, were responsible.
Ochoa and Torres were stopped by police near the crime scene and were described by police as “sweating and nervous,” court records show.
Torres, a Mexican citizen, was also convicted of first-degree murder and sentenced to death in the shootings, but his sentence was reduced by then-Gov. Brad Henry in 2004.
Henry imposed a sentence of life without parole after Mexican government officials raised concerns that Torres was not given a chance to speak with the Mexican consulate after being accused, as required by international conventions.
