Hector Arrande Moya was a client of Gloria Dayton's, and a Colombian drug trafficker who was wanted by the DEA on a federal warrant. He had a history as a sicario for the Sinaloa cartel going back to his teenage years, with seven murders to his credit before the age of 15. He served time in a Mexican penitentiary but was released when he turned 18 years of age. In Mexico he was known as El Fuego due to his practice of setting fire to his victims.
In 2006 he was arrested by the LAPD for possession of 2 oz. of cocaine. A gun was also found under the mattress of his bed. He steadfastly claimed the gun was not his and must have been planted. He was represented in court by Dan Daly, and convicted later in the year, after which he was sentenced to serve a life sentence at FCI Victorville due to the finding of "gun enhancement with federal drug-trafficking." In prison he came in contact with fellow inmate Sylvester Fulgoni, Sr. Working through Fulgoni's son, Moya filed a Sec. 2241 Habeas Corpus petition with the court, alleging gross misconduct by federal agents. Specifically, he alleged that agent James Marco had a confidential informant (Dayton) plant the gun in his room.
He told Fulgoni Sr. about using Dayton as a prostitute, and he believed she had been the person who planted the gun in his room. In April 2013 he was visited in prison by Mickey Haller regarding the connections between Moya, Dayton, and Marco. Moya offered cartel protection to Haller, which he declined at the time. He also offered protection to Haller's client, Andre La Cosse, which Haller accepted.
In the trial of La Cosse for murder, Haller was able to demonstrate Marco's corruption, making it apparent that he had planted the gun on Moya. Moya ultimately won his Habeas case but was then deported back to Mexico. Some months later he sent a photo to Haller showing a dead man hanging from a tree. The dead man appeared to be Marco.
