DALLAS (CBS11) – As the days turn to weeks, the family of missing Dallas mom Marisol Espinosa refuses to give up hope.

“We’re still looking,” says Espinosa’s Aunt Veronica Walls. “Every day we go out… sometimes it’s a party of two, a party of four. As a family, we are continuing to search for Marisol, so we can bring her home.”

Espinosa, a mother of three, vanished December 29th after leaving her home in Pleasant Grove. She was headed to work at the Toni & Guy salon at North Park Center, but never arrived. Since then, family, friends, and even strangers have continued to search and plan to do so again tomorrow morning.

Meanwhile, Dallas Private Investigator John Rosa has become an accidental conduit for tips.

“They’re all similar in the sense that they’re contacting me because they’re afraid to do anything else,” says Rosa, CEO of the EJR Agency. Rosa appeared in a CBS11 news story last week about where else Dallas police should be looking for clues. He says after the story aired, his phone started ringing.

“You do have non-U.S. citizens residing in that neighborhood,” says Rosa, “they’re afraid of the authorities. They may have warrants or tickets. They just can’t identify with the police.”

Then, an anonymous letter arrived. We will not disclose the letter’s full contents as clearly the writer is afraid—referencing a suspect and knowing “what he and his family are capable of.”

Rosa says he is not surprised at the level of concern. “If the house can burn, maybe their house can burn, too. People are afraid, sure. They care for the mother. They care for the kids, they want to help. But they don’t want to endanger their lives in helping.”

Two weeks before Espinosa vanished, her house burned in a fire that family members believed was suspicious. Originally ruled an electrical fire, arson investigators have since reopened their investigation. However, a spokesperson this week declined to provide updates, telling CBS 11 that the results of the review would not be disclosed as they are now part of a police investigation.

Dallas police, meanwhile, continue to insist that Espinosa’s is a “missing person” case and as such there are no suspects. Still, there are plenty of suspicions.

“She’s not one to leave her children unattended,” adds Rosa, admitting that he has a “bad feeling. It’s bad.”

Still family members are unwavering. “Our ultimate goal is to have her home,” says Walls… pleading with an unnamed, as yet unknown, assailant, “just let us have Marisol back, that’s what I plea.”
