"We wanted to make sure that if she would get away from us that we would be able to get ahold of her quick. That someone could help us find her," Crowe said.
That someone is the Craighead County Sheriff's Department.
Rolland said when people go missing, it often takes hours, days, sometimes months to find them.
"When the call comes in and we have this lost person and we search and we search with negative results, only to find the person deceased the very next day or the following night, it's just discouraging," Rolland said.
"Having these volunteers is worth its wait in gold," Rolland said. "When you have an additional ten to 15 people to show up to help in that search, along with the monitoring devices, it's absolutely imperative."
So far, the department has not needed to use Project Lifesaver to find a missing person, and neither has Macie's family.
"I hope we never have to use it, but it's peace of mind knowing that we have it," Crowe said.
"Every parent who has a child that may wander or an elder that may wander, it's important that they have that device," Elks Lodge member Lynn Cooper said. "It could happen at school, it could happen at home, with a friend so this way they're protected whoever they're with."
