ST. PETER, Minn. — A female security guard at the state sex offender treatment center here has been charged with sexually assaulting a male patient committed as a sexually dangerous person.

The complaint, filed recently in Nicollett County District Court, accused guard Claudia Kogo, 57, of Mankato, Minnesota, of having sex with the patient more than two dozen times in late 2017.

The patient reported the relationship started with flirting and progressed to sex, according to the complaint.

Kogo reportedly told a state investigator she kissed and groped the patient, but denied having sex with him. Recordings of phone calls between the two included conversations about their sexual activities, the complaint said.

Kogo is no longer an employee at the treatment center, the Minnesota Department of Human Services reported. 

“Sexual relationships between staff and patients or clients at DHS treatment facilities are unacceptable under any circumstances,” said Chuck Johnson, the department’s deputy commissioner.

Details for this story were supplied by the Mankato, Minnesota, Free Press.
