The ISU Police Department is investigating the theft of the historical MacKay Hall sign.

Authorities say the sign was stolen sometime between Aug. 25 and Oct. 23.

ISU Police currently does not have any suspects, which is why it is turning to the public for help.

“One of the reasons we wanted to put this information out there on social media, as well as contacting other news sources, is because the most important thing is getting the sign back,” said Carrie Jacobs, deputy chief with ISU Police.

Jacobs said the MacKay Hall sign was part of the original building built in 1911 that it is currently valued at about $2,000. That doesn’t count the historical value of the sign.

Jacobs said construction in the area prevented the theft from being reported immediately because ISU Police was checking to see if the sign had been removed during construction.

If students have any information about the missing sign they can contact ISU Police at the 24-hour dispatch number 515-294-4428 or leave an anonymous tip at the Story County Crime Stoppers at 515-382-7577.
