This morning at 9:30 Eastern Time, people across the country will observe a moment of silence to honor the shooting victims of a mass shooting in Newtown, Connecticut.

One week ago a gunman entered Sandy Hook elementary in Newtown and took the lives of 20 students all between 6 and 7 years old, and six adult educators. The shooter also shot and killed his mother in her home.  

In a letter sent to his counterparts across the country, Connecticut Governor Dan Malloy said:

"Let us all come together collectively to mourn the loss of far too many promising lives at Sandy Hook Elementary School. Though we will never know the full measure of sorrow experienced by these families, we can let them know that we stand with them during this difficult time."

At least 28 states have some official plan to participate. 

Many websites will also go dark for a minute at 9:30, including HLN's social-media accounts which will go silent for a while starting at 9:30am.
