DALLAS COUNTY, Iowa — Two central Iowa men have been arrested for allegedly sexually abusing an underage girl at a rural Dallas County residence.

Evidence of the alleged sexual abuse was uncovered in 2024 while the Dallas County Sheriff’s Office says it was assisting the Federal Bureau of Investigation with a case. After months of investigation, multiple search warrants, and analyzing digital evidence, two arrests were made.

Cheyenne Bretsch, 27, of DeSoto, was arrested March 11th and is charged with four counts of third-degree sexual abuse. Ross Bretsch, 56, of Ankeny, was arrested on seven counts of sexual abuse on March 13th.

Both men, who court documents identify as father and son, are being held in the Dallas County Jail.

According to the DCSO, the men sexually abused the same victim during the summers of 2019 and 2020. A search warrant application filed in the case said the victim had originally been enrolled at an archery academy run by Ross Bretsch. She was 14 and 15 years old at the time of the abuse.

An initial hearing for the men is scheduled for March 24th at the Dallas County Courthouse.
