ALPINE, TX (KWES) - The search for Zuzu Verk continues, but more details came out Thursday in search warrants released from the municipal court in Alpine.

Six search warrants were released involving the disappearance of Zuzu, 22.

The warrants say that Zuzu's boyfriend, Robert Fabian, last saw Zuzu between 3 a.m. and 4 a.m. on October 12. Fabian reported her missing on October 14 at 1 p.m.

Zuzu's dog was found running loose in the backyard of her home with its leash still attached to its collar.

A search warrant for a 2005 Gray Ford F-150 revealed that Fabian borrowed the car from a friend in the early morning hours of October 12.

A separate search warrant for a 2016 White Ford Mustang states Fabian was picked up by Christopher Estrada from the 500 block of South 16th Street on October 12. Estrada took Fabian to his home on the 400 block of North Harrison.

The search warrant says that on that same day, Estrada visited a friend around 1 a.m. and seemed distraught and was pacing back and forth.

The friend told authorities that she asked Estrada if he was okay. She says Estrada told her, "I'm fine. I didn't do anything. If they interview me, I have nothing to say."

She said Estrada then contacted Fabian and asked if he could come over. She says he had never acted like this in the past and she knew something was wrong.

A friend of Fabian, Joshua Cobos, told authorities that on Friday, October 14, Fabian went to his gas station and was acting nervous. Cobos said he asked to use his phone and then called Estrada's girlfriend. Cobos said Fabian said, "let me speak to Chris" and walked away to talk in private.

Earlier that day, authorities say Estrada went to the same gas station to get his car washed. Cobos refused because the place was busy.

He told police that Estrada came back to the gas station two more times, each time more eager to get his car cleaned.

A search warrant for Fabian's computer states that the laptop was dropped off at Cobos house, who then turned it over to police.

Cobos said that the laptop contained "items that Fabian wanted to delete from social media."

He told Cobos that he "didn't look good" as a suspect in the disappearance investigation.

Officials released three more search warrants, two for AT&T and one for Celico Partnership dba Verizon Wireless. Authorities say Fabian made two calls to Estrada at 3:15 a.m. on October 12 and contacted him through Snapchat.
