SAN ANTONIO -- A San Antonio mother of three disappeared without a trace. After six grueling months and pages of interviews and witness testimony, investigators are even more focused on finding where she is or who is responsible.

Bianca Carrasco was last seen May 1 at her home in San Antonio. She disappeared, leaving behind three children, a brand new nursing degree in oncology, and a very anxious family.

"She was a very strong woman,” said Bianca’s mother, Barbara Talamantez. “She was very passionate about whatever it was she was doing. She was a great mother. But of course, like all of us, we have our own inner demons."

Talamantez says that those demons may have been her downfall. Bianca, an Odessa native, lived in San Antonio with her husband. It was a marriage that, police say, was on its last legs.

"It's my understanding they were going through marital problems, that divorce was contemplated or in the process of being filed,” said Officer Doug Greene, a spokesman for the San Antonio Police Department.

According to San Antonio police, Bianca and her husband, Joe, got into a fight the night she disappeared. He told investigators that he left with their youngest child, back to Odessa where he worked. He reportedly left the other two children at home, assuming their mother would be back.

How she left the home and whether she left on her own free will is a matter of debate.

"Of course, I immediately thought he did something to her,” Talamantez said.

Carrasco’s mother and sisters say that they suspect her husband had something to do with it, citing anger issues and their impending divorce.

But Joe Carrasco’s attorney, Joseph Hoelscher, argues that his client had no idea she was missing.

"We would like to know where she is too,” Hoelscher said.

Hoelscher explained that the kids were initially removed from Joe’s custody to live with members of Bianca’s immediate family after she disappeared. All three have since been returned.

He says that Joe is more concerned with caring for them than answering to accusations about his involvement, but claims his client has been cooperating with the investigation.

As for SAPD, they say they can neither prove nor rule out foul play, but they haven’t given up either.

“They're constantly reviewing the case,” Officer Greene said.

That’s not good enough, says Talamantez, who added that she’ll never stop looking, no matter how long it takes.

"What rock would you not pick up and turn and look if it was your child?” Talamantez asked. “When do you stop. How do you stop?"
