Investigators reported that Van Groll felt "afraid that if she doesn't do what he wants, Kratz will throw out her whole case."
A second woman came forward early last week to claim similar harassment, saying Kratz had offered to let her attend an autopsy. In an e-mail written to Gov. Doyle, the woman claimed to have met Kratz online in December 2009. On a dinner date, the woman alleged, Kratz divulged to her the details of an ongoing murder investigation in which a woman was believed to have been killed by her boyfriend.
A few days later, a third woman came forward to claim she, too, had been harassed via text message by Kratz.
Maria Ruskiewicz told the AP she met Kratz in 2008 about a previous drug case. Ruskiewicz said that after she left the meeting, she received several texts from Kratz that escalated into sexual harassment.
"The reason ... I'm coming forward is he abuses his power, not only with women, but with women in certain situations who are extremely vulnerable to his authority," Ruskiewicz, 31, an Appleton, Wis., native, told The Associated Press in late September.
In the week that followed, another two women leveled similar accusations, ABC New's Wisconsin affiliate WBAY reported.
Doyle, the governor, a former district attorney and state attorney general, began proceedings to investigate the complaints, a process that could have concluded with Kratz's forcible removal.
The investigation into Kratz's alleged harassment will continue whether he is in office or not, one investigator told WBAY.
