BILLINGS - Faculty at Beartooth Elementary are asking for the public's help in identifying a vehicle associated with vandalism of their playground late Friday night.  Beartooth Elementary Principal Travis Niemeyer says a parent awoken by a loud vehicle Friday night emailed him about joy riders leaving donut tracks on the school's property. When Niemeyer checked out the tracks Saturday morning, which left large chunks of sod and packed mud ridges, neighbors came out offering to check their Ring doorbell cameras, hoping they may have caught the vandals. Principal Niemeyer says he was shocked someone would do this and has had to close off a section of the playground to avoid any students twisting their ankles in the three to four inch divots left behind.
