"I just want my baby home and that's all I want," said Anna Cuevas, Mark Ysasaga's mother.
Ana Cuevas said she hasn't seen her 15 year old son in a little more than a month.
It doesn't seem like that long but to her it's an eternity.
"It's been hard. It's a day to day process. Everyday I have to think I got to get up and do this," Cuevas said. "And then go to work and do what I got to do but then still thinking where I need to go, Where I need to look, who I need to call."
Dozens of volunteers turned out in Buddy Holly Park today wearing shirts with Ysasaga's name and picture on them looking for any clues they could find.
"A lot of the public has really helped us," Ysasaga's grandmother, Juanita Ysasaga said. "And I really feel like the police and the troopers and the sheriff's department, everybody in that area has really helped out too."
Earlier this week Investigators obtained security video from the Walmart off Marsha Sharp and Avenue Q that showed Ysasaga was there with some friends.
Detectives also found out that after Ysasaga left the store he went to a house in the 3100 block of
That's where he was last seen walking from the area.
These clues give Ysasaga's family hope, but for now the search continues.
"I'm planning to do it until my son comes home or until we find him," said Cuevas.
Cuevas plans to continue to conduct these searches in different areas across town.
