DALLAS (CBS11) — Dallas police officers joined in the search for a missing Dallas mother on Sunday.

Marisol Espinosa, 34, was last seen Tuesday leaving her home in Pleasant Grove to go to work at North Park Mall.

After speaking with police officers, Espinosa's mother, Rosemary, said, "They have something and I feel very strongly about it."

Rosemary Espinosa said the officers told her they had several "developing leads."

Espinosa's Chevy Tahoe was discovered Friday abandoned at the Las Lomas Apartments near Highway 12 and Pemberton Hill Road. Her purse and belongings were still inside the vehicle.

On Sunday friends and family held a prayer and then a candlelight vigil.

Espinosa's boyfriend of six years, Faustino Vasquez, was the last to see her on Tuesday when she left for work.

Vasquez said with young children, he does not believe she willingly disappeared.

"That's not like her. She wouldn't do that," he said. "It feels not like a dream (but) a nightmare that I want to wake up from it."
