A 35-year-old former cop is in the Benton County jail suspected of approaching girls in Columbia Park and offering them money to perform sex acts.
Ryan Graichen was arrested by Kennewick police detectives after he was identified by four girls in connection with two separate cases in early summer, police said.
Graichen, a former Portland police officer, was charged Thursday in Benton County Superior Court with two counts of sexual exploitation of a minor and three counts of sexual abuse of a minor.
He is accused of approaching three teenage girls in Columbia Park on June 13 and offering them each $300, alcohol and marijuana if they would go back to his house and be filmed while he performed a sex act, Deputy Prosecutor Anita Petra wrote in court documents.
Never miss a local story.
He said he wanted to film them with their tops off while he masturbated, documents said.
On June 15, he approached a teen boy and girl and asked them if they were interested in going back to his home and putting on a show for him, documents said.
He specifically offered the girl $500 if she would watch him masturbate, Petra wrote.
When Kennewick police officers searched Graichen's home, they found a locked gun safe with 14 firearms inside and a black CD case containing 30 DVDs and a mini video cassette, documents said.
On the right side of the safe in a zippered case marked "GREAT" was a three-ring binder with pictures of teenage girls wearing bikinis and other photographs that were more pornographic in nature, documents said. The pictures reportedly showed breasts and private parts of teen girls engaging in a variety of sexual activities.
Some of the girls appeared to be 15 to 16.
The black case also contained a mini video cassette, an electronic media storage card, a DVD, a matching swimsuit bikini, a bikini bottom and condoms, Petra wrote.
Investigators also searched an armoire and found a computer, suspected marijuana, two digital cameras, a video camera and an I-Phone.
Graichen was identified by all of the victims, documents said.
Investigators suspect there might be additional victims who were approached by Graichen in Columbia Park since March and who might have been offered money for some type of performance or modeling.
Anyone with information about similar incidents should call Kennewick police Detective Bill Dramis at 585-4208.
Graichen resigned from the Portland police force in 2007 while under investigation for filming high school girls at a school dance and basketball games and zooming in on their private areas, according to news service accounts.
He was a school resource officer at the time.
He was hired in Portland in 1998. A statewide police policy panel later revoked his police certification for violating the state's moral-fitness standards for police.
