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. Daughter Carlie, is at right seated next to her husband and son-in-law to Martin, Chris. 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)
