The Montgomery County Sheriff's Office is assisting the Walker County Sheriff's Office in the search for a 55-year-old woman who went missing in the Sam Houston National Forest Friday morning.

According to MCSO Capt. Bryan Carlisle, Walker County is leading the investigation and search while Montgomery County is proving man power along with equipment such as drones.

"They are going to lead the investigation until they let us know we need to do something different," Carlisle said.

The woman has been identified as Theresa Kirkpatrick.

Carlisle said Theresa was hiking in the forest with her husband Allen Kirkpatrick, 51, when the two were separated around 8:30 a.m. Allen continued to search for her until about 4 p.m. until he reported her missing to another person.

It was not clear who called 911 to report the woman missing. The woman is reported to have a medical condition but what it is was not released.

Carlisle said Texas Parks and Wildlife is also on scene to assist with the search.

"I expect we will devote a tremendous amount of resources to the situation," he said.

No other information was available.
