Cheyenne Police investigators are trying to find out who broke 29 windows at Hebard Elementary School Saturday, according to police spokesman Officer Dan Long.

Laramie County School District 1 officials say the school, located near Fifth Street in the southeast part of Cheyenne, has been vandalized before, although not this badly. Long says police believe the windows were broken with a rock, adding that so far no citations have been issued in connection with the vandalism.

But he says the investigation is ongoing and police are looking at possible suspects in connection with the incident. Anyone with information on the case is being asked to contact the department, according to Long.
