A Portland police officer placed sexually harassing calls on his bureau-issued cell phone to three female police officers and a number of other women, including a 16-year-old girl he had encountered as a patrol officer, according to court documents.

Joseph E. Wild, 28, a Portland Police Bureau veteran of four years, pleaded not guilty to 20 counts of telephonic harassment and 41 counts of official misconduct in a Multnomah County courtroom Monday afternoon.Investigators said in an affidavit that on several occasions, Wild placed sexually explicit calls to three female Portland police officers who were in training at the state police academy in Salem. He placed the calls on his cell phone during his regular patrol shifts, according to court documents.

The documents also allege Wild has harassed civilians he aided.

A 16-year-old girl reported to police she received phone calls from a man she did not know, who claimed he had had sex with her March 24.

The girl said she had been intoxicated that day and didn't remember any sexual contact.

Detectives traced the phone call to Wild's cell phone and discovered the officer had taken the girl to a facility for missing juveniles after receiving a radio call about an intoxicated person.

While searching Wild's cell phone records, they found 50 phone calls between February and April 2009 had been placed to a phone number belonging to a 14-year-old girl. When detectives interviewed her, the girl said she had received numerous phone calls from a man who had made sexual statements that frightened her and made her cry.

Nineteen of the 20 counts of harassment against Wild are for calls made to the 14-year-old.

Wild's phone records also brought detectives to a female victim of a domestic violence call that Wild had apparently responded to because he had written down information about the incident in his field notebook.

When detectives contacted the woman, she told them she had received phone calls from a man she did not know who threatened to "come to her house and rape her," the court documents said.

In another phone call shortly after, the man told her he was in her basement.

The woman told police she was alone in the house with her daughter at the time and was extremely frightened. According to the affidavit, Wild placed eight calls to the woman over 27 minutes.

All the victims reported that the phone calls were unwanted and sexual in nature.

During an interview between detectives and Wild on May 4, he reportedly admitted to placing the phone calls to the female officers and to ignoring their requests to stop calling.

Wild was arrested Friday.

During the arraignment, Circuit Judge Julia Philbrook said she had reviewed the court documents and "would not be surprised" if more charges were brought against Wild.

On Monday, Wild was still an employee of the city of Portland, according to police spokeswoman Detective Mary Wheat; he requested a court-appointed lawyer at the arraignment.

Scott Westerman, president of the Portland Police Association, was in attendance at the arraignment, but refused to comment about the case.

"We're here to show Joey a friendly face," Westerman said. "But as far as the allegations are concerned, the union does not have a particular role in it at this time."

Wild is being held in the Multnomah County Jail in lieu of $132,500 bail.

Wheat said despite the investigation into Wild, residents of Portland should not feel apprehensive about police officers.

"All organizations from time to time have issues with employees," Wheat said. "We want to make sure the public can feel safe with Portland police officers."
