The Brown County Sheriff’s Office arrested a Green Bay man this week with a long rap sheet of sexually abusing animals.

Fox 11 reports that authorities arrested Sterling Rachwal, 53, and charged him with sexual gratification with an animal, mistreatment of animals causing death, and burglary. The Brown County Sheriff’s office said that at this time they are only investigating the case, and no charges have been filed. They declined to give specifics.

Earlier this year, Rachwal was arrested for sexually assaulting a horse. A barn owner reported to police that the horse’s rectum was bleeding. It’s unclear if the recent arrest has any connection with the horse incident. He’s expected in court in June.

Rachwal has several prior convictions for abusing animals, dating back to 1993 when he was convicted of sexual gratification with an animal and mistreatment of animals causing death. He was sentenced to eight years in prison but was released in 1995 after the state appellate court reversed his charges.

In 1996, he was convicted of burglary, bail jumping, criminal damage to property, and mistreatment of animals. He was deemed “guilty but not guilty by due to mental disease/defect.” In May 1997, he was committed to the Mendota Mental Health Institute. He was released in 2008.

In 2010, Rachwal was found in a horse barn, reportedly with latex gloves on, and arrested. He was later convicted of disorderly conduct and served 90 days in the Fond du Lac County jail, then sent back to the Mendota Mental Health Institute. He was released again in April 2015.
