FORT BEND COUNTY, Texas -- Sheriff's deputies say a helicopter search crew successfully located a 79-year-old man who walked away from a home earlier this week.

Muhammad Shabbirhing was last seen after walking away from a home at 1915 Gable Cove Court in the Richmond area. Authorities were concerned about the man's condition because he has a cognitive impairment.

FBCSO previously tweeted he was last seen on Berdette Road at about 7:30 p.m. Monday.

The sheriff's office used a helicopter and ATVs to search the Walnut Creek and Bridlewood areas. Deputies say he was located Wednesday morning standing in water not far from where he was last seen.

Medical personnel are currently looking him over to assess his condition.
