When asked if there are any laws that protect the families of the missing, Allen said this is a gray area because while states do have laws regarding fraud and harassing communications, they don't always apply to this type of activity.
"A lot of this is just simply not traceable and a lot of it doesn't really rise to the level of criminal activity," Allen said. "It's just cruelty and insensitivity."
Despite the hardships and painful memories, some family members of the missing dedicate their lives to the cause. Dwayne Baker now works with the CUE Center.
"When I go to search for someone else's loved one, I'll give 110 percent," Baker said. "When I get in the field, I'll be the one that will go anywhere [Caison] needs anytime because I'm going to find that person, if possible, because I know that my boy is looking down thinking, 'Way to go, Dad.'"
Baker uses his own experiences to help families whose lives turn to turmoil when a loved one disappears and his message for others is simple: "Have respect for the families of the missing."
