Ohio mercury spill

Authorities say the Morrow County courthouse in central Ohio is to remain closed today following yesterday's evacuation due to a mercury spill.

Sheriff Steve Brenneman says the poisonous substance was found in hallways on two floors of the building. Most of the building was slowly evacuated yesterday afternoon and people were asked to remove their shoes so they could be checked for contamination.

Some employees were asked to stay in their offices until clean up crews arrived at the site in Mount Gilead, about 40 miles north of Columbus.

Brenneman says the source of the mercury is unknown, and there are no reports of people being sickened.
