Texas Equusearch searching for missing Katy woman

Justin says his mother was diagnosed with dementia about a month ago but has been exhibiting symptoms for more than a year. Despite that, Justin says her disappearance is very unusual. 

"Scared, delusional, who knows?" ," Justin said. "She has dementia already, so add being outside for over 36 hours with no food, no water. She’s probably dehydrated, tired, [and] scared. She probably just doesn't know what to do or what’s going on." 

More than 6300 people and counting, have now joined search and rescue efforts organized through a Facebook group called "Find Sherry". 

On Thursday, volunteers met at Second Baptist Church then dispersed on foot and on horseback to comb through every inch of a mapped-out search grid.

Jake Stovall has helped law enforcement search for missing people for the last 18 years with his organization, Gulf Search and Rescue. 

"Right now we have three possible sightings that we are tracking down," said Jake Stovall.  

He says approaching someone with dementia may scare them farther away and instead, urges anyone who sees her, to call the authorities right away. 

"First thing is, don’t approach her," Stovall said. "She’s going to be confused and scared. Don’t ever actually try to get her to come with you, most likely they’ll flee and hurt themselves and run away more. So just try to take a picture of her. If you have a sighting, take a picture, and then stay behind her. Stay far away, 20 feet away. Call us. Call her daughter, Courtney. Call 911 or the Sheriff’s Department."
