Brownwood firefighters found the body of a person who was “most likely” homeless after they extinguished a small grass fire in a field behind Commerce  Square early Friday morning, Brownwood Assistant Police Chief James Fuller said.

Firefighters saw the body on a burned mattress after putting out the fire in a small patch of trees around 1:20 a.m., Fuller said. Authorities have not yet identified the person or determined age or gender. The body was taken to the Tarrant County Medical Examiner’s Office, Fuller said.

“It was raining and sleeting when we were out there,” Brownwood Fire Marshal Buddy Preston said.

Preston did not have a cause for the fire but said there is “nothing suspicious at this time.”

The Brownwood Fire Marshal’s Office and Police Department are conducting a joint investigation to determine the cause of the fire and to identify the body, Fuller said.

Kelly Crenshaw, pastor of New Beginnings Church, at 1001 Belle Plain in Brownwood, heard about the death and posted on Facebook:

“Very sad to hear that why found someone that had died out behind Commerce Square (Thursday) night. Not sure but rumored that it was a homeless person.

“Please, anyone and everyone in Brownwood, know that we at New Beginnings are doing what we can to help the homeless population. When it gets extremely cold we try to open our doors so someone can have a warm place. It breaks my heart that this happened.”
