Twin teenage brothers who died during an after-hours visit to a luge-bobsled track are being remembered as dynamic members of their school communities, while prayers continued for other boys who were hurt in the crash.

Jordan and Evan Caldwell, 17, were killed and six other male teens were injured early Saturday while using a personal sled/toboggan to go down the bobsled track at Canada Olympic Park.

Their sled hit a large gate used to separate the luge and bobsled tracks.

In a statement published Sunday by the Calgary Police Service on Facebook, the boy's family said their deaths leave "a huge void."
