CLARKSVILLE, Tenn. (WKRN) – Deputies need help finding a burglary suspect after a terrifying home break-in.

Authorities told News 2 a suspect broke into a home on Retriever Court Monday night in Clarksville.

The homeowner woke up to his house alarm going off and immediately locked the bedroom door and went into his storm shelter.

The victim said the room saved his life. While he originally built it to protect himself from weather, he knew it could also serve as a panic room.

At The Safe House in Nashville, they install vault doors regularly on cinder block rooms for home owners.

“We build and design panic room and safe rooms they can be used interchangeably,” owner of The Safe House Mark Brasfield told News 2, adding that they have been in the safe business for more than two decades.

“We are the largest safe specialty store in the southeast–safe, vault doors and storm shelters.”

Brasfield told News 2 he has been busier than ever with people looking specifically for panic rooms.

“We’ve probably seen a 50 percent increase in sales, if I had to put a number to the increase in sales this past year,” he explained.

The Safe House has installed around one hundred and fifty vault doors for rooms the past year for everyone from football players to musicians.

“I kind of attribute it to our uncertainty in the country and stuff.”

The Clarksville victim said he had more of a storm shelter door, not a vault door, but Brasfield says they still serve as a form of protection.

“If someone came in your house and you got in your storm shelter and they don’t have a gun they aren’t going to get into that.”

The aggravated burglary suspect fled the scene before deputies arrived and no items were taken during the incident.

Anyone with information is asked to call investigator Jesse Hedrick at 931-648-0611 ext. 13407 or Crime Stoppers at 931-645-8477 or text 274637 (CRIMES).
