One well-know code began in 1994. “Code Adam” essentially locks down the store while the employees do a sweep to look for a missing child, according to Time.

"Code Adam" started after 6-year-old Adam Walsh was abducted from a Sears in Florida in 1981. **Sensitive info about to be posted here** Sixteen days after his disappearance, his severed head was found floating in a canal by two fishermen.
