ODESSA - Saturday saw the face of Rene Sanchez posted on car windows and handed out to people along 42nd Street.
Rene's mother, his wife and many others combed the parking lots of Target, Office Depot and other stores.
"Revive somebody's memory or maybe they'll say "Well, hey, I've seen this man,' and they'll give the police a call," Rene's Mother, Herminia Sanchez, said.
Rene vanished four years ago outside his Odessa home, leaving all belongings behind.
His mother said that doesn't add up.
"He would call me and say 'Mom, I'm thinking about putting a fence up on the house. What do you think?'" she said. "That's not a man that will disappear overnight."
For Rene's wife of 10 years, Esther Armendarez, it doesn't matter how long he's been missing when the pain she feels is constant.
"No one really understands unless they're going through it or they've gone through it," she said. "He's on my mind 24/7. I'm just hoping that we find him, bring him home."
Back in May, the family received some new hope.
The Odessa detective who's been investigating Rene's case for the last year-and-a-half said the last tip they got was that he was at a shopping center on 42nd Street.
Family members hope someone can lead them to Rene and bring him back to his two children, a young boy and girl ages five and seven.
They were only one and three at the time of Rene's disappearance, young enough to only have a few memories with their father.
"The little girl asks for him," Herminia said. "Nobody can take the place of her Dad."
"Just keep Rene's story going. Keep it out there," Esther said. "It could be that peace that we're looking for."
Sanchez would now be 40-years-old, about 5'8" tall and 180 lbs. He has a large dragon tattoo on his right inner arm area.
