A group of 20 teenagers from Newtown is heading to Colorado next month to help rebuild homes devastated in last year's flooding.

It's the third annual service trip run by Ben's Lighthouse, a nonprofit founded to help Newtown's children recover from the December 2012 massacre at Sandy Hook Elementary School. The organization is named after 6-year-old victim Ben Wheeler.

The first group traveled to Oklahoma in 2013 to help with cleanup following a string of destructive tornadoes. A second group visited Colorado last summer.

Ben's Lighthouse Chairman Rick Haylon says the trips are designed to give the teenagers perspective and to empower them to help others during a time when many feel helpless.

The teens also plan to meet with survivors of the Columbine High School shooting and visit the memorial to its victims.
