North Texas Police are now using dogs in the search for a missing Fort Worth woman and her 7-year-old son.
An Amber Alert was issued for Lisa Underwood after she failed to show up Saturday for her baby shower. Monday morning, Underwood's SUV was found in a creek near Denton.
"Locating the vehicle is a major step forward in the investigation but we can't say exactly how close we are to solving this incident," said Lt. Gene Jones of Fort Worth Police.
Authorities are also searching New Mexico, Oklahoma, Louisiana, and Arkansas for any signs of the pair.
