Search for Missing Texas Mom Julie Ann Gonzalez Continues

AUSTIN, Texas (CBS) Police are continuing to search for missing Texas mom Julie Ann Gonzalez. Gonzalez disappeared over a month ago, but with very little evidence and a lack of new leads many questions remain unanswered.

According to the Austin Police Department's spokeswoman Anna Sabana, the case is still open and being investigated.

Unfortunately, she also asserts that there is no physical evidence to indicate that Gonzalez was a victim of foul play, and without probable cause, police cannot search her abandoned car or look at her phone records, reports CNN.

The 21-year-old mother was last seen by her estranged husband George De La Cruz on March 26. De La Cruz and Gonzalez were in the process of getting a divorce; however, he maintains that he had nothing to do with her disappearance and says he is willing to take a polygraph test.

De La Cruz told CNN that when Gonzalez came to pick up their two-year-old daughter at his house she "looked completely different. She kind of looked sad."

Gonzalez told him that she would be back later, but she never returned to pick up her daughter.

"She's always been responsible. She always looked out for the best interest of her 2-year-old daughter. That was her main concern, 24-7," Gonzalez's Aunt Dora Cooper told CNN.

Julie Ann's family fears the worst because they do not believe would willingly leave her daughter.

The family of missing mother Julie Ann Gonzalez prays for her safe return and asks that anyone who has information regarding her whereabouts contact the Austin Police Department at 512-974-5000.
