Leonardo Quintana went before a civil service board Thursday to appeal his dismissal from the Austin Police Department.

In May 2009, Quintana shot and killed Nathaniel Sanders in an East Austin apartment complex while investigating a suspicious vehicle. Quintana said Sanders was reaching for a gun. A grand jury decided not to indict Quintana over the shooting. He was later fired over a DWI he received in Leander in January.

Presented as evidence during the hearing was a photo of Quintana holding an AR-15 assault rifle on Facebook.

One of his former supervisors said the integrity of the badge was compromised.

"We're held in this police department, and as a manager in it, we are on 24-7. Being involved in a critical incident, we should know better,” Jessica Robledo with APD said. “And to present ourselves in something like that, I don't agree with it. I don't tolerate it. I have zero tolerance for stuff like that.”

Quintana told a superior officer he had a "grueling day" that led to some heavy drinking before he was busted for his DWI.

Officials with APD Internal Affairs said Quintana drank several “Saki Bombs” at a sushi bar in South Austin before heading to a strip club for more drinks.

Quintana then drove 30 miles to Leander with a fellow female officer in the vehicle.

Stephen Fleming was Quintana's supervisor at APD.

"It really showed a real disregard for his safety, her safety and for some of the ideals the department stands for as far as drinking and driving,” he said.

Five hours after his DWI arrest, Quintana’s blood alcohol level was .088. Experts estimate his level could have been .192 when he was pulled over, three times the legal limit.

Adam Loewy is the attorney for the Sanders family. He said the writing has been on the wall for Quintana for quite some time.

"We believe he should have been fired for the shooting. We believe he should have been fired for a number of incidents before the shooting and so personally this doesn't surprise me this happened,” he said. “There were many red flags in this officer’s career that predicted something like this occurring."

Austin Police Chief Art Acevedo agreed Quintana does not deserve to serve under his command.

“I wish him well, I don’t wish any ill will to Officer Quintana, but I don’t think he can be an effective member of this department,” he said.

The arbitration hearing is expected to wrap up Friday.
