INGHAM COUNTY, MI -- Ingham County Prosecutor Stuart Dunnings III allegedly paid for things like rent, YMCA memberships and methadone treatments in return for sex, according to witness statements.

Six witnesses provided affidavits, which detail the husband and father of three's alleged abuse of power and relationships with prostitutes.

The women who were designated as prostitutes in the affidavits are referred to as W-1, W-2, W-3, W-4 and W-5; with W-6 representing the woman Dunnings allegedly induced into prostitution.

The affidavit was filed by Ingham County Sheriff's Office Detective Amber Kenny-Hinojosa.

Dunnings, who has served as Ingham County's prosecutor since 1997, faces 15 charges across three counties over his alleged patronage of prostitutes from 2010-15. He faces 10 counts of engaging in prostitution, four counts of willful neglect of duty and one count of pandering prostitution.

If found guilty on all charges, the 63-year-old faces 261/2 years in prison.

Michigan Attorney General Bill Schuette's office said the 2015 FBI human trafficking investigation of Tyrone Smith led to Dunnings. Smith, who had previously served 15 years for second-degree murder, recruited Lansing-based women for his interstate sex operation, according to a press release from the Justice Department.

Further federal investigation into Smith, who remains without a sentence, led to Ingham County's top prosecutor, according to the press release.

It is not noted whether the six witnesses listed in the affidavit were involved with Smith's sex trafficking operation or not.

W-1 allegedly posted on the website Escort Vault, which led to Dunnings reaching out for her services. The two arranged to meet with Dunnings paying $200 for sex at a Lansing-based Red Roof Inn, according to the affidavit. For the next five years, W-1 and Dunnings met for sex as much as three to four times a week, the affidavit said.

According to the witness, Dunnings paid her rent and gave her money for things unrelated to sex. The prosecutor allegedly wanted to be W-1's only customer, which she allegedly declined.

W-2 was introduced to Dunnings through his request to have sex with more than one woman at once, according to the affidavit. According to the statement, W-1 videotaped W-2 and Dunnings having sex on at least one occasion.

Dunnings and W-2 allegedly had sex more than 200 times, which typically involved dinner and a hotel room at the rate of $100 for 30 minutes, $160 for an hour and $140 an hour for multiple hours, the affidavit said.

Dunnings, who paid for W-2's phone bill, groceries and YMCA membership, allegedly made it clear to her that he was the prosecutor of Ingham County, the affidavit said.

When W-2 told Dunnings she was addicted to heroin, he started paying $80 a week for methadone treatments and even attended Narcotics Anonymous meetings, the affidavit said. When W-2 was arrested for possession of drug paraphernalia, Dunnings allegedly took the prostitutes' mother money for bond, it said.

Dunnings and his brother, Steven, allegedly each had commercial sex with W-3 on multiple occasions, the affidavit said. It is noted in the affidavit that W-3 regularly had "observable bruising on her body" and "multiple, visible needle tracks on her arm from heroin use."

Dunnings then met W-4 through W-3 at the Magnuson Hotel in Lansing for sex, the affidavit said. W-4, who got into prostitution through crack and heroin addictions, would eventually refer to Steven Dunnings as a "regular customer," it said.

Steven Dunnings is charged with two counts of engaging prostitution.

W-5 and Dunnings only had commercial sex once, according to the affidavit. The two met at W-5's apartment in Holt, for which Dunnings allegedly paid $150 for about 15 minutes of sex, it said.

In 2010, W-6 sent an email to Dunnings regarding assistance with her custody dispute, the affidavit said. W-6 met Dunnings at his office, where she allegedly revealed to him that the father of her child was domestically abusing her, it said.

It was allegedly during the pair's second meeting that Dunnings proposed a solution to her financial issues; he would pay her for a sexual relationship, the affidavit said.

"W-6 was initially shocked by this proposition, and did not immediately accept," the document reads. "After thing the proposition over, she felt she had no choice but to accept." W-6 estimates that Dunnings III paid her about $600 every two weeks during the times they would meet for commercial sex, the affidavit said.

Dunnings III's position as Ingham County Prosecutor influenced W-6's decision to engage in commercial sex with him, the affidavit said. She both hoped that he would help her in her child custody dispute, and feared that he might cause her problems if she refused his proposition, it said.

Dunnings and W-6 allegedly had sex at multiple locations, which include her trailer park home in Lansing, the Fairfield Hotel and Causeway Bay Hotel, also both in Lansing, the affidavit said.

The ensuing charge from W-6's allegations, pandering, is punishable by up to 20 years in prison and represents the most serious crime the prosecutor faces.
