Plano police have released new surveillance video showing a missing Fort Worth woman walking with a friend shortly before she went missing early Saturday morning.
Christina Marie Morris, 23, was last seen near the Shops at Legacy.
According to police, Morris had been visiting friends on the 5700 block of Scruggs Way.
In the surveillance video, Morris and a friend walked into the parking garage at 5715 Legacy Drive before they separate to go to their cars.
Morris's silver Toyota Celica was later found nearby, but there has been no trace of her.
Police said the man in the video has been very cooperative is not considered a suspect in the disappearance. He and Morris have been friends for a long time, police said.
Morris's family said they hope the video may generate new information.
"I am angry. I am hurt. I am losing hope, but I still have faith. It has been seven days. That is a long time," said Morris's mother, Jonni McElroy.
Family members returned to the area Friday to pass out flyers and ask anyone with information to come forward.
"Very little sleep. We are just beside ourselves," said sister Sara Estes.
Christina Morris is described as white, 5 feet 4 inches tall and weighing about 100 pounds, with brown eyes and blonde hair.
The latest news from around North Texas.
The family said Christina Morris is always in touch with them, but hadn't been as much the past few days.
Thursday evening, a search team of more than 50 volunteers, mostly made up of friends, fanned out to scour a wooded area selected by Plano police.
The search area is bounded by Parkwood Boulevard and Hedgcoxe Road and is located a short distance away from where Morris' car was found.
Police requested the team of volunteers to help locate any potential evidence or belongings of Morris' that may have been discarded by an assailant.
"Hopefully we're gonna find her alive. That's the main hope that we have. But there's always the unknown," said Quinn Meredith, who referred to Morris as a "friend-of-a-friend."
Meredith volunteered to use his all-terrain vehicle to search the fields and along the tree lines.
One group of volunteers located some clothes in a field, which will be tagged as potential evidence, according to David Tilley, with the Plano Police Department. The clothes, however, do not match the description of what Morris was last known to be wearing.
Plano police asked that anyone with information about Christina Morris contact them at 972-424-5678.
