A man was urinating and masturbating in Pioneer Park during a middle school cross-country meet on Thursday, charges allege.
Matthew Lyman Tippets, 38, was scheduled to appear Friday in Yellowstone County Justice court on one felony charge of indecent exposure.
According to charges, Pioneer Park hosted a regional cross-country meet Wednesday afternoon for around 800 middle school kids.
One man attending the event with his 9-year-old daughter told investigators they were walking to a checkpoint when Tippets pulled out his penis and began peeing in front of them. A group of sixth-grade girls was running by at the time, charges say.
Another witness said she saw Tippets masturbating near a checkpoint.
