St. Matthews, S.C. (WACH)--Investigators are searching for a Fort Jackson soldier that vanished from his home.

Sergeant Robert Larson was reported missing by his wife Pamela on Sunday.

Pamela told authorities that her husband was in the driveway working on his Jeep Wrangler Saturday evening, she asked him to help with housework and he never came inside.

"He wasn't there I started to call him every hour on the hour until his phone was no longer on and it was the most terrifying experience because I don't know where he'd go," said Pamela Larson.

The Purple Heart recipient has completed several tours overseas tours.

During a mission in Iraq Sergeant Larson survived a severe brain injury, he is on medication to help with his healing process.

"When's he's on them he's the same man I married and when he's off of them it's a struggle," said Pamela Larson. "You just kind of have to take the good with the bad and remember that he has to heal."

Calhoun County Sheriff Thomas Summers stated that in this case there is little to go on since it looks like Larson left on his own.

"There's nothing unusual for a grown man to go off to blow some steam occasionally but she knew within a matter of hours something wasn't right," said Sheriff Summers.

According to investigators Sergeant Robert Larson was last seen at his home in the Sandy Run Community in Calhoun county Saturday evening October 6, around 7pm.

He is described as 6'1, 190lbs with brown hair and hazel eyes.

Larson was last seen driving his 2009 Black Jeep Wrangler 4-door with South Carolina license plate PH5752.
