Missouri Governor Jay Nixon is urging Missourians to join the nation and pause today to remember the victims of the school massacre in Newtown, Connecticut.

Nixon and governors across the country are calling for people to observe a moment of silence at 9:30 a.m. in their local time zones.

That’s the hour of the shooting last Friday at Sandy Hook Elementary School.

The gunman killed 20 first-graders and six adults before committing suicide.

Nixon said in a news release that the “moment of silence across the country represents the sorrow deeply felt by our nation.”

In Newtown the moment of silence will be followed by church bells. The pause will happen at 9:26 a.m.exactly a week after the school massacre began.
