Family of shooting victim Glenn Martin speak out about their father in Castle Rock, Colorado.

DENVER, CO - JULY 6: Family members of Glenn Martin address the media during a press conference at the Robert Christensen Justice Center in Castle Rock, Colorado on July 6, 2015. From right to left are his daughter Carlie, son-in-law, Chris and daughter Janelle, far left. The family asked not to use their last names. Their father, Glenn Martin, was shot and killed by what investigators think was an errant bullet from a high powered rifle. The family was camping at Rainbow Falls Park in the Pike National Forest when Martin was shot while setting up the family's camp. No one saw a shooter and they are trying to figure out if it was an errant bullet that killed Martin or an intentional act. (Photo By Helen H. Richardson/ The Denver Post)
