A tri-county search is underway for a missing Minnesota teen.

19-year-old Brandon Swanson was reported missing early Wednesday morning. Right now, crews are focusing on an area near the town of Taunton, MN, where searchers found Swanson's car Wednesday. They were able to find it by tracing his last cell phone message.

What makes this search unique is its location -- Yellow Medicine, Lyon, and Lincoln Counties essentially border each other. Consequently, several different law enforcement agencies are working together to find Swanson.

They marched on foot, soared through the sky, and rode on four wheels. More than 75 people searched for the Marshall teen after he had reportedly drove his car into a ditch.

Searchers brought out dogs and trolled in boats, but haven't had any luck. The Yellow Medicine River is so high and moving so fast it's making it difficult for them to do their search.

Still, no one is giving up here.

Speaking on behalf of the Swanson family, Laurar Hundley made a plea. She said, "The family misses him very much. If anyone has any information please contact the Lyon County Sheriff."

If you have information on Swanson's whereabouts, call the Lyon County Sheriff at (507) 537-7666.
