Chattanooga, TN (WRCB) -- Caleb Brown alert and walking is what his parents describe as a miracle after dealing with two months of intensive therapy and surgeries.

Tim Brown said quick thinking of the people who were there that tragic day in October, is the reason his son is here today.

"I want to say thank you to the people who were there and helped save his life," says Brown.

Caleb's story filled the airwaves, from Nashville, to Chattanooga, even Athens, Tennessee

Athens Police officer Rob Davis took a half day from work to see Caleb's visit to Chattanooga.

"I had to be part of it. Something told me I have to," says Davis.

Camille Ward dealt with a similar family tragedy when her brother and father were injured in a boating accident. She saw this as an opportunity to counsel the family in tough times.

"To see him now playing and making noise and grabbing at things is so great," says Ward.

Spring Hills Road Baptist Church Pastor James Julian spent many nights praying with the family

"Having them come to the church and see him walk around and the family rejoice is something special and I'm happy to be part of it," says Julian.

At times, Caleb seemed more like a normal two-year-old than a recovering trauma patient. His mother says his fight for survival has influenced thousands who never met him.

Caleb will undergo an evaluation at Vanderbilt University Thursday morning and as of right now, the Van Buren County Sheriff's Office has called off the criminal investigation.

Early on, there were reports of teens throwing rocks down the falls the day Caleb was hit.

Sheriff Grayson Beasley said there's not enough evidence to pursue criminal charges.
