Long-time felon sentenced to 100 months in federal prison

United States Attorney’s Office continues to go after violent felons who possess guns and ammunition


Indianapolis – United States Attorney Josh J. Minkler announced today that an Indianapolis man with an extensive criminal history was sentenced in federal court following his conviction by a jury last fall. Ruben Mancillas, 50, was found guilty of illegally possessing ammunition stemming from his arrest for firing a handgun into the air in his east side neighborhood in the middle of the afternoon. U.S. District Judge William T. Lawrence sentenced him to 100 months (over eight years) in federal prison.

“Guns and ammunition in the hands of convicted felons, particularly those with long criminal histories, leads to much of the violence in Indianapolis,” said Minkler. “These individuals are on notice: we will catch you, take you to trial, convict you and you will go to federal prison.”

On an August afternoon in 2015, neighbors on Indianapolis’s east side witnessed Mancillas in a heated argument with his girlfriend. They called police after he belligerently fired a handgun several times into the air in the densely populated neighborhood. Hearing sirens, Mancillas fled but he was quickly apprehended by Indianapolis Metropolitan Police Department officers, who also, with the assistance of a ballistics-sniffing dog, found dozens of rounds of ammunition at the scene.

Mancillas was sentenced to 100 months in federal prison in part due to his lengthy and violent criminal history. He fired the gun into the air just six weeks after being discharged from parole. Prior to this incident, had been convicted roughly 15 other times for a variety of felonies and misdemeanors. In all, over the past 35 years, Mancillas has been convicted roughly 20 times and arrested on over a dozen other occasions. This record demonstrated that Mancillas is an increasingly dangerous individual who has a complete disregard for the law. So he was sentenced accordingly.

case was investigated by the Indianapolis Metropolitan Police Department and the Federal Bureau of Investigation.

According to Assistant U.S. Attorney Nick Linder, who prosecuted this case for the government, Mancillas must serve 3 years of supervised release following his sentence
