Eleven days after Sydney Marquez was last seen, police have confirmed that they’ve reviewed surveillance footage showing her on the day she disappeared. However, they claim that the footage offered little information that could help them track her down.
Marquez, 24, was last seen on December 11 near a shopping center in the 9100 block of Bellaire Blvd in Houston, Texas, according to a missing persons flyer issued by nonprofit search and recovery organization Texas EquuSearch.
According to the flyer, she was last seen wearing gray pants, a gray hoodie and tennis shoes. Additionally, she stands at 5′ 4″ tall, weighs 120 lbs and has one tattoo of a leaf clover on her left wrist. Her hair was described as a red/brown/orange color and was styled in a short haircut.
Ten days after she disappeared, authorities reviewed surveillance footage from the Bellaire Blvd shopping center on Sunday, December 21. The footage showed Marquez walking northbound down the sidewalk on Ranchester Drive, according to KHOU 11.
Texas EquuSearch’s Tim Miller, who has been assisting in the search for Marquez, told the outlet that Marquez appeared to be walking normally in the footage and there were no apparent signs of distress.
“We’re back to square one and again it’s (a) process of elimination, this area is now eliminated, so we have to keep moving forward,” Miller said.
Texas EquuSearch also recently conducted a day-long search for Marquez in Houston alongside her parents.
“She suffers from mental illness, which makes finding her quickly even more urgent,” the organization wrote in an update on Monday, December 22. “No parent should ever have to spend day and night searching for their missing child-but this family refuses to stop hoping, and neither do we.”
Marquez went missing when she traveled from El Paso to Houston to meet with a friend, according to a Facebook post from the AWARE Foundation Inc. According to the nonprofit organization, which is dedicated to assisting families with missing loved ones, Marquez left her phone, clothes and makeup behind in her abandoned car near Houston’s Chinatown neighborhood.
“Her family is deeply worried after hearing she may have last been spotted at a bus stop, partially unclothed,” the organization wrote in a post shared on Wednesday, December 17.

While speaking to KHOU 11, Miller said he does not believe the friend Marquez was visiting had anything to do with her disappearance.
“He was 100 percent cooperating and the father and him actually went to HPD and really questioned him and everything, I think they did everything that was necessary to do,” Miller said of the friend.
