DENVER (AP) -- Colorado observed a moment of silence on Friday to remember the 26 people killed at Sandy Hook Elementary School in Connecticut.

Bells also tolled in Denver at 9:30 a.m., the time when the shooting started on the east coast.

Gov. John Hickenlooper and governors across the country called for the moment of silence and also asked government buildings and places of worship to ring bells 26 times in honor of those who died at the school.
