A 38-year-old San Antonio woman has been sentenced to 87 months in federal prison for her role in a conspiracy to purchase machine guns and attempt to smuggle them into Mexico.

Additionally, authorities said Yadira Mauricio Ybarra, 38, has been sentenced for bank fraud.

A U.S. District judge also ordered that Ybarra pay $133,846.09 restitution for the bank fraud, and be placed under supervised release for a period of 3 years after completing her prison term.

On July 12, 2011, Ybarra pleaded guilty to one count of possession of a machine gun.

According to court records, on April 19, 2011, federal authorities arrested Ybarra and Willy Mendoza, 24, after they paid $10,000 to an undercover agent and took possession of ten firearms--4 fully-automatic machine guns and 6 semi-automatic assault rifles.

Court records also show that both Ybarra and Mendoza knew the firearms were going to be taken to Mexico.

On Oct. 6, 2011, attorneys said Mendoza was sentenced to 70 months in federal prison, followed by two years of supervised release after pleading guilty to possession of a machine gun.

On Feb. 7, 2012, Ybarra pleaded guilty to one count of conspiracy bank fraud. By pleading guilty, Ybarra admitted that from April 28, 2009 until July 6, 2009, she conspired with others to steal approximately $130,000 by forging signatures of various account holders at the Wells Fargo Bank, Las Palmas branch, in San Antonio.
