"We have charged him and we have a warrant for his arrest," said Anaheim Police Sgt. Rick Martinez.
Wadley, 56, is suspected of leaving pornographic photos of himself on the windshields of women's vehicles while the victims worked out at Toyon Park in Anaheim Hills.
Police were able to connect the incidents using forensics. Martinez said they retrieved a fingerprint on a photograph that came back to Wadley.
"We found photographs of male genitalia, several different shots of this person," said a victim last week who only wanted to be identified as Jill.
Jill is one of several women who say they found similar photos on their cars and on nearby running trails last month in the early morning hours.
"They have been almost put in a bit of a shrine to himself and propped up where people can see them," Jill said.
Another victim who also did not want to be identified, said, "The fact that they knew we were there in the morning was creepy."
"Forensics work along with a fingerprint that we were able to retrieve from one of the photographs has identified the suspect as Mr. Wadley," Martinez said.
Wadley is also charged with indecent exposure in a separate incident as he passed a woman walking alone Thanksgiving morning on the same trails, located about a half-mile from Wadley's home, police said.
"He doesn't have his pants completely on," Martinez said. "As a matter of fact, they're down to his knees exposing not only his genitalia, but his rear end. At that point, she did say a few things to the individual, who then took off running."
E-mail warnings about the lewd activity began circulating in the community weeks ago. Police served a search warrant on Wadley's home after identifying him as a suspect.
No one answered the door at Wadley's home Wednesday. He is suspected of being out of the country, but on his way back to the U.S.
Neighbors said he lives with his wife of more than 30 years, their daughter and her fiance. Wadley retired from the Huntington Park Police Department last June, 30 years after joining the force.
"It is certainly disheartening, troubling, when you find out who the individual is," Martinez said. "Regardless of who that person is or what position they may have held, the fact remains that this is criminal behavior."
Police are trying to find Wadley. They believe he may be out of the country on business, but is on his way back to the U.S.
Authorities said there may be more victims. Anyone who has information or is a victim is asked to call Anaheim police at (714) 765-1960.
