A series of dots helped them make a dash for it.
An elderly couple used their knowledge of Morse code to escape from an assisted living facility in Tennessee, according to a report.
The husband and wife, who have dementia and Alzheimer’s disease, were able to decipher and memorize the code to an electronic door lock at the Elmcroft of Lebanon home, the Nashville Tennessean reported.
They were missing for about 30 minutes on March 2 before a stranger found them walking about two blocks from the facility, according to state Department of Health documents obtained by the newspaper.
The husband said he had “previously worked with Morse code in the military” and used that experience to learn the code of an electronic keypad as staffers punched it in.
He and his wife were then able to unlock the door of the home’s secure memory unit — and make a break for it.
State officials fined Elmcroft of Lebanon $2,000 as a result of the escape.
The facility said it had changed all of its exit codes and would prevent similar incidents by checking on residents more frequently.
The escapees will also be scheduled for “walking time outside the facility with a staff member present,” state records show.
“The safety of our residents is the top priority at our senior living community. We are thankful both residents were returned to the community safely,” the company said in a statement. “We reported the situation to the state and their family immediately after it happened and fully cooperated with the state during its review.”
