ALPINE, TX -- A major break in the case of missing North Texas woman Zuzu Verk.
Police in West Texas arrested her boyfriend, Robert Fabian, Saturday morning. He's charged with "tampering with or fabricating physical evidence by concealing a human corpse."
The arrest comes one day after a U.S. Border Agent discovered human remains in a shallow grave near Alpine, not far from where Zuzu was last seen alive.
Police have not identified the remains. The medical examiner is expected to make that announcement sometime next week.
21-year-old Zuzu Verk is from Keller and was studying at Sul Ross State University. The night she disappeared back in October, Fabian's downstairs neighbors say they heard the couple arguing.
"We just heard one, 'shut the eff up,' and that was it," John Franco told KOSA-TV.
Then hours later... a loud thump.
According to search warrants obtained by KOSA-TV, Fabian then called his friend Chris Estrada twice. Estrada denies covering for his friend.
But Zuzu's friends say before she disappeared, she feared for her safety, "She mentioned that she didn't feel safe. Her tires recently had been slashed. She said, 'I don't think Robert slashed my tires, but he may have done it.'"
Regardless of the arrest, Robert Fabian's family has said from the beginning that cops have the wrong guy.
"He's asking himself the same question that everyone is asking -- where is Zuzu?" his sister Jocelin Carillo told KOSA-TV. "Like my mother said, he loves her."
Well now, it'll be up to a jury to decide if that love turned to rage.
