Prosecutors say Portland real-estate developer and Democratic Party activist Terry Bean engaged in sex with an underaged boy in 1979, providing the 16-year-old with alcohol and drugs. The teenager later tried to kill himself after Bean broke off the relationship, court records say.

The records were filed by prosecutors late Thursday in Lane County Circuit Court as part of an ongoing criminal case against Bean. Bean in November 2014 was charged with two counts of third-degree sodomy, a felony, and one count of sexual abuse in the third degree, a misdemeanor, allegedly involving a 15-year-old boy.

Prosecutors say they wanted to introduce evidence of Bean's "prior bad acts" dating back to 1979 into the current case to establish a pattern of sexual abuse by Bean. The events described in the filing are beyond the statue of limitations.

The filing comes a week after Bean asked a Lane County judge to have the criminal charges against him dismissed. The Eugene Register Guard reported earlier this week that Bean's attorneys are seeking what's called a "civil compromise" to the criminal charges against Bean. As part of the deal, Bean has reportedly reached an agreement with his alleged victim in the current criminal case. Prosecutors oppose a dismissal of the charges.

The filing also reveals new details about the current charges against Bean and his former boyfriend, Kiah Lawson.

A Lane County grand jury in November indicted Bean and Lawson on charges that they'd had sex with a 15-year-old while in Eugene for a University of Oregon football game in September 2013.

In 2014, WW reported on Bean's efforts to protect his reputation following the bitter breakup he'd had with Lawson. After the story ran, the Portland Police Bureau launched an investigation into allegations that Bean had sex with one or more minors.

Bean is a co-founder of the Human Rights Campaign, the nation's largest gay rights organization, and is prominent in state and national politics. He was the largest Oregon fundraiser for President Barack Obama's two victories and in the past visited Obama in the White House and flew with the president on Air Force One.

Prosecutors in Thursday's filing say they believe the allegations dating back 36 years help establish a pattern of behavior by Bean. The filing says the evidence shows Bean's "motive, opportunity, intent, preparation, plan [and] knowledge" of illegal behavior.

The alleged victim from 1979 is now a 52-year-old doctor in California who says the abuse occurred when Bean was 30 and he was 16. The victim stepped forward in January because he wanted to help make sure Bean did not "keep on abusing young boys." He expressed concern that Bean had the money to escape the criminal charges with "minimal damage," the filings say.

The alleged victim says he met Bean at Bean's Eugene home in June 1979. When it became clear Bean was interested in a sexual relationship, the alleged victim told Bean that he was 16. He said Bean knew he was a virgin when they first had sex in a Eugene apartment.

The filing says he and Bean eventually engaged in both oral and anal sex in several encounters in 1979. The filing also says Bean took him across state lines for sex, which prosecutors say was a violation of the federal Mann Act.

The alleged victim says Bean broke off the relationship in December 1979 because, as Bean is quoted as saying in the documents, the teenager was "lousy in bed." The alleged victim said that he ran into Bean at a party a year later and was distraught when Bean snubbed him. The filing says the alleged victim attempted suicide by taking an overdose of painkillers. He reportedly was sent to a mental hospital after that.

Updated at 8:55 pm with a statement from Bean's attorney, Derek Ashton:

A civil compromise was

filed on July 2 with a statement by the “alleged victim” that he has no

interest in prosecuting this case and never did.  A civil compromise

represents a resolution of criminal charges that satisfies both parties.

There is a hearing on this compromise on Thursday, July 16.The

law allows a civil compromise in this case.  However, the special

prosecutor is objecting for dubious reasons. For almost two years, Terry

Bean has been the victim of Kiah Lawson’s schemes and lies which have

led law enforcement to harass Mr. Bean’s friends, seek out old

acquaintances and threaten him with further prosecution unless he admits

to events that did not occur.The

special prosecutor has aggressively sought evidence against Mr. Bean,

and relied on untrustworthy witnesses recruited by Kiah Lawson as part

of his ring’s attempt at extortion. The latest charge being made by the

special prosecutor to the Court is about a man who alleges that 36 years

ago, Mr. Bean and his now deceased former partner had sexual relations

with him when he was underage.  Since Mr. Bean’s partner died of AIDS 25

years ago, there is no other witness to deny this scurrilous charge and

the prosecutor knows this.We look forward to the hearing next week and an end to this defamation.
