A Southern California corruption case unraveled in dramatic fashion after federal agents discovered tens of thousands of dollars hidden underground at the home of a longtime local politician, according to the NY Post.

Ricardo Pacheco, a former Baldwin Park councilman, was sentenced to 18 months in prison for taking bribes while in office. Investigators recovered $62,900 buried in his backyard, part of more than $83,000 ultimately seized from him.

Federal prosecutors said Pacheco used his position to help private interests win favorable treatment from the city. Much of the misconduct involved companies seeking approval to operate marijuana businesses in Baldwin Park.

Pacheco also took money from a police officer who was secretly cooperating with the FBI. Authorities said he received $37,900 from the officer and later backed a police association agreement valued at more than $4 million over three years.

The Post writes that another former elected official, ex-Compton Councilman Isaac Galvan, was caught up in the same investigation. Galvan admitted giving Pacheco $70,000 in exchange for assistance with marijuana permits and separately acknowledged failing to report more than $500,000 in income.

Both men received 18-month federal prison sentences. Pacheco was fined $10,000 and ordered to surrender nearly $220,000, while Galvan was ordered to pay more than $323,000 in restitution.

After pleading guilty and leaving office, Pacheco began cooperating with federal investigators and helped build cases against several other people tied to local government and the marijuana business.
