They listened and listened until the beeps and boops finally made sense.

And then it was time to go.

A husband and wife briefly escaped from a secure memory unit at an assisted living facility in Lebanon last month by using military experience with Morse code to decipher and memorize the code to an electronic door lock, according to Tennessee Department of Health documents obtained through a public records request.

The couple, who have dementia and Alzheimer’s disease, are not identified in the state records. They went missing from Elmcroft of Lebanon for about 30 minutes on March 2 before a stranger found them walking down a road two blocks from the facility, according to the documents.
