He is one of Ellen Wolf's clients, but only mentioned in context by various characters.
He allegedly committed a carjacking murder and was prosecuted and convicted by Miguel Prado. After the trial, however, Detectives Joey Quinn and Angel Batista uncovered new information from Zack Adelman that not only exonerated him for the murder, but also provided another suspect for the murder.
Lieutenant Maria LaGuerta relayed this information to Miguel, but he ignored it and instead pushed for Hines' sentencing. After this, LaGuerta went to Ellen Wolf with this new information. Wolf then appealed to the court for a reversal of Hines' sentence which angered Miguel.
After Miguel murdered Wolf, it is unknown if Hines remained incarcerated for his alleged crime.
