A 32-year-old Mankato man has been charged with criminal sexual conduct and incest over allegations that he sexually abused his 2 daughters multiple times for several years. Bo Elliot Kellerhalls made an appearance in court Tuesday for 10 counts of criminal sexual conduct, 2 counts of criminal sexual predatory conduct, and 1 count of incest. The victims are Kellerhalls’ 9-year-old and 15-year-old biological daughters. The 15-year-old told police her father started touching her when she was around 4 years old. The 9-year-old claimed that he started sexually assaulting her when she was 7. Authorities learned of the crimes after the youngest daughter told Kellerhalls’ girlfriend about the abuse.
