Michael Johnson, 22, a former student at Lindenwood University in Saint Charles, may have knowingly infected more than 30 unsuspecting partners, with HIV.
Prosecutors found hidden cameras and examined Johnson’s computer, finding over 30 videos of Johnson having unprotected sex.
Many of the videos appear to have been filmed on the campus of Lindenwood University in Saint Charles,
“It’s safe to say that numerous of those videos were taken inside his dorm room; we know that because we recognise the furniture,” Mr Lohmar said.
They believe that Johnson’s sexual partners did not know that he had HIV, the virus that causes AIDS, or that they were being filmed.
Authorities are asking that anyone who may have had an intimate relationship with Johnson or may have information about him come forward.
Johnson could spend life in prison, if convicted.
