The reward in the case of a missing college student from the Fort Worth area has been raised to $200,000, authorities in Alpine announced Monday.
The donations are mostly from private sources, WFAA-TV reported.
Zuzu Verk, a 21-year-old student at Sul Ross State University in Alpine, has been missing since Oct. 12, when she went on a date with her boyfriend, Robert Fabian.
Fabian was named a suspect in Verk’s disappearance last week, but police have not arrested him. Fabian’s family members and a friend, Chris Estrada, have also been named persons of interest in the case.
No significant developments had been made in the case over the weekend, WFAA reported.
According to search warrants obtained by WFAA, Fabian called Estrada twice during the early morning hours of Verk’s disappearance.
A separate warrant said Fabian borrowed a Ford F-150 pickup early Oct. 12.
John Franco, who lives directly below Fabian in an apartment complex across from Sul Ross State University, told WFAA that he could hear arguing and pacing the night Verk disappeared.
Another search warrant, for Estrada’s Ford Mustang, says that in the days after Verk’s disappearance, Fabian was acting “very nervous” and that Estrada tried to get his car cleaned three times at a local auto shop, WFAA reported.
Authorities have covered more than 500 square miles in the search for Verk.
The vast, thinly-populated search area in southwest Texas has stretched from Alpine to the U.S.-Mexico border, about two hours away.
Verk is from the Keller area and graduated from Timber Creek High School in far north Fort Worth.
