South El Monte Mayor Luis Aguinaga agreed to plead guilty to a federal bribery charge this week after admitting to a seven-year scheme in which he collected cash payments from a city contractor, officials said.

In his agreement, the mayor admitted to taking bribes every two to three weeks from a contractor doing business with the city, according to officials. The bribes would range from $500 to $1,000 and it is estimated Aguinaga collected $45,000 during the entire timespan.

While Aguinaga’s admission of bribes is shocking, he is by far not the first San Gabriel Valley politician to be caught accepting, soliciting or offering bribes.

Here are several other scenarios involving various local politicians who were also involved in bribery schemes.

Shrimpscam

An FBI sting in the late 1980s resulted in a series of political corruption charges for four local politicians. In that case, a fake shrimping company offered bribes in exchange for favorable legislation.

Dubbed “Shrimpscam,” the sting resulted in the convictions of State Senator Joseph Montoya, D-Whittier; State Senator Frank Hill, R-Whittier; and Assemblyman Pat Nolan, R-Glendale; and Board of Equalization Member Paul Carpenter, D-Cypress between 1990 and 1995.

Montoya received six years in prison in 1990 for extortion, money laundering and racketeering. Nolan received 33 months for racketeering in 1994. Hill was sentenced to four years for extortion and money laundering, following an unsuccessful appeal in 1995.

Carpenter’s conviction in the “Shrimpscam” case was ultimately overturned, but he was later sentenced in a separate case on counts of obstruction of justice and money laundering. He fled to Costa Rica before being captured roughly a year later. He was sentenced to seven years in prison, but only served four.

Temple City Trio

This small town was rocked by a bribery scandal in 2009 when its then-mayor, former mayor and a council candidate were all indicted on charges of bribery solicitation.

Judy Wong, Cathe Wilson and former council candidate Scott Carwile faced accusations from a local developer who alleged each demanded money in exchange for support of a $75 million project on Las Tunas Drive and Rosemead Boulevard.

Judy Wong eventually pleaded no contest to multiple bribery and perjury charges and was sentenced to 16 months in prison. She was released in May 2011.

Wilson was also imprisoned for bribery and perjury in May 2011 for seeking a $10,000 bribe related to the development project. Wilson originally pleaded not guilty and fought the accusations before being found guilty. She was sentenced to four years in prison, but was allowed to go into “alternative custody” in May 2013 by earning credit for being discipline-free and doing programs while in prison. She was 80 years old when she was released.

Carwile pleaded guilty to perjury, but was not sentenced to any jail time.

A fourth person involved and referenced in some allegations, former Temple City councilman David Capra, pleaded guilty to a misdemeanor campaign finance violation and resigned from the council in the fallout of the bribery allegations.

Rosemead’s John Tran

Former Rosemead Mayor John Tran was sentenced to nearly two years in prison and ordered to pay $38,000 in restitution to a developer — the amount in bribes he allegedly received — after agreeing to a plea deal in 2013. He pleaded guilty on Nov. 18, 2013 to one felony count of attempted witness tampering by corrupt persuasion and one felony count of making a false statement to the FBI.

Previous charges of bribery concerning programs receiving federal funds, two counts of extortion and two counts of attempted witness tampering by corrupt persuasion were dismissed.

Tran was also ordered to attend substance abuse and gambling programs as part of his sentence.

The Calderon Dynasty

A political family dynasty was decimated in 2016 when two of the most prominent Calderons, former state Sen. Ron Calderon and his brother and former state legislator Tom Calderon, both agreed to plea guilty in a bribery scheme. Tom Calderon made a deal first, agree to one county of money laundering. Prosecutors are asking for a sentence of no more than one year.

Ron Calderon’s deal came a week later in June 2016 when he agreed to admit to one count of mail fraud that could carry a sentence of nearly six years in prison.

In the plea agreement, Ron Calderon admitted to accepting bribes from Michael Drobot Sr., former CEO of Pacific Hospital of Long Beach, who hoped to reap millions of dollars in illicit profits from a separate fraud scheme. Ron Calderon also admitted to accepting bribes from undercover FBI agents posing as independent filmmakers who wanted changes to California’s Film Tax Credit program.

Another 23 counts of public corruption, mail fraud, wire fraud, bribery and money laundering were dismissed as a result of the deal.

Alhambra Duo

Former Alhambra mayor John Parker Williams and developer Frank Liu admitted to offering $25,000 cash to an Alhambra councilman in exchange for his vote to approve Liu’s 2004 project proposal.

Liu pleaded guilty to one felony count in 2007, received no jail time and was fined $10,000.

Also in 2007, Williams was sentenced to one year in jail and fined $1,000.

Three years later, Liu was back in Alhambra seeking approval for another senior housing complex project.

Marijuana Dispensaries and Joe Serrano

Joseph Serrano, a former Santa Fe Springs councilman, was sentenced to two years in prison in 2012 for bribery and had to pay $10,000 in restitution. Serrano said he took $11,500 in bribes to help pay for treatment for an ill niece even though he had $600,000 in assets. In exchange for the bribes, he told a business owner he could provide information on city plans regarding medical marijuana dispensaries and help him stay in business.
