Walworth County deputy arrested, sexual assault charges filed

A Walworth County Sheriff's deputy is in jail. He’s charged with 19 felonies – including sexual assault and child enticement.

"These are very substantial charges that carry very substantial penalties," said Court Commissioner Peter Navis.

Gerardo Baca, 36, appeared before a Walworth County judge via Zoom on Friday. He was arrested Thursday.

"There are numerous allegations in the complaint suggesting Mr. Baca engaged in harassment or intimidation type behavior with some of the victims," said Special Prosecutor Sue Opper.

A 16-page criminal complaint states the sheriff's deputy sexually assaulted some of the victims while they were highly intoxicated. In some cases, recording them without consent and threatening them afterward.

"They were unable to defend themselves or protect themselves in any manner," said Defense Attorney Nathan Opper.

Investigators said Baca's victims included co-workers, an intern and a 17-year-old girl.

"He has a life he has worked long and hard to build, and he is now facing the prospect of if being torn down," said Nathan Otis.

Baca was hired as a Walworth County sheriff's deputy in 2017. He resigned Friday. His attorney says he's been cooperating with the investigation.

"We have significant amounts of evidence that contradict a claim that there was non-consensual sexual activity with at least two of these victims," said Otis.

Walworth County Sheriff Kurt Picknell requested the investigation be transferred to the Waukesha County Sheriff’s Department in order to ensure an independent law enforcement investigation. Additionally, the Walworth County Sheriff’s Office is conducting a full internal investigation. 

"The Walworth County Sheriff's Office is a very good agency with great people. I take this matter seriously, and we continue to serve the mission of public safety," the sheriff said in the release.
