Texas EquuSearch has joined the search for a missing El Paso woman who was last seen more than a week ago in Houston’s Asiatown.
Authorities say 24-year-old Sydney Marquez was last seen on Dec. 11 on Bellaire Boulevard between the Sam Houston Tollway and South Gessner Road.
Marquez was wearing a gray hoodie, a beige shirt, gray pants, and white tennis shoes when she went missing. She’s about 5 feet, 4 inches tall and 120 pounds with brown eyes and red hair. Her family said she has a four-leaf clover tattoo on her wrist.
Family said she was in Houston to visit friends.

Raul Marquez is still hoping someone remembers seeing his daughter. The family lives in El Paso and said they got a call from Sydney’s friends telling them she left and never returned.
“Witnesses are saying that they saw a young lady who was distraught, walking in circles, keeping to herself, that they offered her blankets,” he said.
Raul said his daughter graduated from Texas A&M with a neuroscience degree.
“She was a superstar … bright, fast, crunched numbers in her head,” he said.
Her abandoned car was found in a tire shop parking lot near the intersection of Bellaire Boulevard and Ranchester Drive.
Authorities said Marquez suffers from mental illness.
Her family said she may have gotten onto a bus at the Harwin and Gessner bus stop on Tuesday, Dec. 16, around 11:45 p.m. They said she may have been wearing a blanket. Houston METRO said it is working with the Houston Police Department to try to get video footage from inside the bus.
The family shared surveillance video from a tire shop near Bellaire and Ranchester that they hope will help lead to where she might be.

“Sydney, it’s Christmas, baby. Let’s go home and open some gifts. I love you. I can’t wait to hug you,” he said.
Marquez’s family issued this statement about her disappearance:
“Our family is deeply concerned and heartbroken as my sister, Sydney, remains missing. She has not been located, and we are asking for the public’s help in bringing her home safely.
“At this time, we are attempting to shift the focus and share only confirmed information. We are grateful to the Houston community and the media for helping spread awareness. Although I have emailed Detective Leonel Avila to ask which hospitals law enforcement has reached out to ensure no gaps in coverage, I have not heard back yet.
“Our family’s priority is Sydney’s safety and privacy, and we ask for compassion and respect as we continue this search.”
