Rochester Police are investigating eight broken windows at the Strong Museum of Play Dancing Wings Butterfly Garden.

Officials believe sometime after 2 a.m. on Monday, exterior windows of the garden were damaged.

The windows are double paned and the shatterproof interior panes remained intact, so none of the butterflies escaped, according to officials.

Although investigators aren’t ruling out vandalism just yet, they say the damage could also be weather related. Police say that wind has shattered windows at the Butterfly Garden before.

Rochester Police also said they have yet to hear of any other businesses being impacted as well. They’re reviewing security camera footage from the area as well.

No matter what the cause, it’s going to be a costly fix. The Strong’s spokesperson, Shane Rhinewald, says the cost will be “in the thousands.”
