A St. Louis-area massage therapist is facing allegations in three separate venues that he secretly videotaped women as they changed clothes.

The suspect, 38-year-old Kirk Jackson of St. Charles is charged in St. Louis city, St. Louis County and St. Charles County. All told, he faces 19 charges of invasion of privacy.

In the St. Charles County case, authorities allegedly found 140 videos of women in bathroom stalls, tanning beds and massage therapy rooms.

He was already in custody on those charges when Chesterfield police learned of possible crimes at a business in their city.

In St. Louis, police say Jackson secretly videotaped nude or partly nude women while he was working at Gateway EDI, where he was hired to perform services for employees.
