CLAYTON, Mo. – A disturbing invasion of privacy case is under investigation by St. Louis County Police could be expanding this morning. Officers believe two people already accused of photographing a young girl in a mall bathroom took more pictures of young girls using bathrooms at several other places.

St. Louis County Police compiled the following list of addresses along with dates and times. Police have pictures of unknown girls, photographed without their knowledge. Call the St. Louis County Police investigator working the case at 314-615-8618 if your family was there.

Sgt. Adam Kavanaugh said, “All of the images we have involve young girls who have been in restrooms in those locations.” He describes it as one of the worst cases he’s seen in 17 years. He added, “It appears they were using some kind of camera stick to kind of go on top of the stalls or underneath the stalls.”

The St. Louis County Police Department says these are the locations and times where girls may have been photographed without their knowledge:

Heather McDorman and Zachary Hamby face invasion of privacy charges after reportedly photographing an 11-year-old girl in a South County Mall bathroom March 12th.

Now police have identified seven places Mcdorman and Hamby photographed girls between February 27th and March 12th.

Sgt. Kavanaugh said, “We have a pretty close proximity of the times based on the time stamp of the images, so we’ll be able to narrow that down.”

We found Hamby had a prior conviction for impersonating a police officer and his Florissant neighbors told us he was a peeping tom, but nothing comes up in McDorman’s history. And she lists prior jobs in home health and as a school bus aid.

We found she recently posted on Craigslist “I’m looking for a girlfriend.” She posted her pictures- saying “hey girls! My name is Heather.” Then we found another ad – “Are you looking for a babysitter?” with a similar introduction — ‘Hello, my name is Heather.”

Sgt. Kavanaugh added, “We’ve come across some ads that are concerning with her apparently looking for babysitting jobs as well and we’re still working on that angle.”

He said police have no evidence of babysitting victims, however, Mcdorman and Hamby are also charged with sodomy involving a four-year-old.

St. Louis County Prosecutor Bob McCulloch said, “I’m very confident we’ll have additional charges.”

McCulloch says they’ll be investigating for awhile and that the public’s input is key.

He said, “The more information people have, the more information authorities have and the better off we are.”

Meanwhile, Fox2/KPLR 11 spoke to two young women who believe they were at the South County Center on one of the dates the incidents took place.

“March 5, because that was my friend’s birthday,” said one of the teens, whose name we’re not revealing because they are minors.

“It’s kind of disgusting and frightening for me to hear that happened,” another one said.

The two high school students said they spend a lot of time at South County Center and both were there during the month of March several times.

“I would feel very upset and taken advantage of, knowing that someone was taking pictures of me, it’s not okay,” one teen said.

One of the high school students described the situation as “so gross, it’s hard to hear about.”
