Cory Green picks out a balloon to tie his message to as he, his family and their friends get set to send messages aloft in a balloon launch on Monday. Cory and his four siblings lost their parents, Brad and Krista Howe a year ago Monday when they were killed in a collision with a drunk driver. Friends and relatives joined the Howe, and Green children and their guardian Karla Green, Krista’s sister Monday to pray and commemorate the anniversary of Brad and Krista’s deaths.
