MONTICELLO, Iowa (AP) – Hundreds of people volunteered to have their heads shaved this weekend in an effort to set a world record and show their support for a 5-year-old boy who lost his own hair during treatment for cancer. The boy, Austin Smith, is the son of Monticello police chief Britt Smith. KCRG-TV reports that Austin’s grandfather was the first person in line among the more than 400 people who had their heads shaved within one hour on Sunday.

Organizers say they needed at least 372 people to have their heads shaved. They will present the figures, along with videos and photos of the event to the Guinness Book of World Records.
