NASHVILLE - Authorities say that a mother and toddler have been located in Memphis after their disappearance led to a search by West Tennessee authorities.

The Shelby County Sheriff's Office says 26-year-old Katie Lin Barnes and her son, 16-month-old Landon Cole Barnes, were found Wednesday afternoon at a friend's house in Memphis.

The sheriff's office says the mother was taken to a hospital. The child and the mother's vehicle were handed over to the TBI Memphis and the Decatur County Sheriff's Office.

The Tennessee Bureau of Investigation had issued an endangered child alert earlier Wednesday.

The agency said Landon's grandfather returned to his home in Parsons to find Barnes had packed up and left. She texted her father about 5:45 p.m. Tuesday, saying she did not want to live.
