A 63-year-old woman went missing for three days in Houston, Texas, before being found alive in George Bush Park thanks to her dog. Sherry Noppe was found at 3 a.m. by a group of volunteer searchers after they heard her dog barking. Officials said Noppe was shaken up and had some cuts and bruises, but was able to make a speedy recovery. Her black lab, Max, is being called a hero for helping signal searchers with his barking. Noppe was recently diagnosed with dementia, but despite her memory loss, was said to be very familiar with the park's trails.
