Missouri Capitol Police continue to try to find out who placed small "target" stickers next to the Capitol office doors of at least six state lawmakers Tuesday.
And why.
Senate President Pro Tem Rob Mayer, R-Dexter, said the Highway Patrol also had been asked to investigate.
"We want to find out who conducted this type of action (and) bring them to light," he said, adding that both lawmakers and potential troublemakers should know "this type of horrible conduct will not be tolerated by this Senate body. We all respect each others' safety and security."
Law officers declined to comment on their probe.
The small, orange stickers appeared between 12:30 and 1:30 p.m., state Sen. Robin Wright Jones, D-St. Louis, said.
"There was no note. No message," she said.
At least five Democratic senators received a sticker, placed on the hallway nameplate next to their office doors.
"A few of the senators removed them, only to have them replaced by bigger stickers, later in the day," Sen. Jolie Justus told colleagues.
At least one House Republican also received a sticker.
