A person called authorities around 8:15 a.m. local time after recognizing Courtney Roland from news coverage, authorities said.
Brian Perroni, a reporter with sports news site 247Sports and who described himself as a family friend, told NBC News that Roland's auto, purse and phone were found in the Galleria mall area Sunday afternoon. However, that's not the last time loved ones had word of her, so it doesn't appear that that is when she disappeared.
It was not immediately clear why Roland was under the overpass.
"We do not suspect any foul play or any kind of suspicious activity attached to this incident", Cruz said. Police later said she was found in the area.
"She seems pretty confused about everything", said Houston Police.
Family and friends reported Roland missing at the weekend. Police found Roland's phone in the vehicle and her purse was found at a nearby business, according to authorities.
Roland covers Texas A&M athletics for Rivals, a Yahoo!-owned online publication focusing on college sports.
Courtney Roland, 29, a sports reporter for AggieYell.com, was last seen around 4 p.m. Saturday wearing a Remington hat and camouflage.
The search for Roland went viral after the woman's friend said she got a text from Courtney saying she believed she was being followed by a suspicious man who tailed her out of a Walgreens. Roland and her roommate meant to meet up later that day, but she never appeared. She was anxious that she was being followed by a blue truck leaving Walgreens, location unknown.
The journalist's roommate, Autumn Vara, said Ms Roland's vehicle was broken into six weeks ago.
On Sunday, Courtney's mother reportedly received a odd text from her daughter's phone. "And I know Courtney would be praying for you, because that's the way she was. She cared for people".
Anyone with information is asked to call the Houston Police Department at 832-394-1840.
