Through the affidavits we’re hearing for the first time what Robert Fabian told police the day after Zuzu Verk disappeared and why Chris Estrada quickly became a suspect as well.

What was supposed to be a romantic dinner on the night of October 12th turned out to be anything but.

"We just heard one, like you know, shut the F*** up and that was it," said Robert’s downstairs neighbor John Franco.

The court documents paint a disturbing picture as to how and who may have buried Zuzu in a shallow grave just outside of Alpine.

“This is what they’ve done,” said Zuzu’s mom Lori Verk.

Lori is referring to Robert and Chris.

That night Zuzu arrived at Robert’s apartment just after 10 p.m. for dinner and a massage.

At least that’s what he told police.

But the couple’s date took a turn according to Robert once he brought up an ex-girlfriend.

He told police the two began arguing and “things got heated.”

Originally Robert said he walked Zuzu out of his apartment and watched her leave between two and three that morning.

It wasn’t until investigators brought up his downstairs neighbor, John Franco that Robert changed his story saying he left his apartment while Zuzu was still there to go think about their relationship.

But right before Robert left, John and his girlfriend said they heard a loud thump.

"We can hear him pacing back and forth, like all over the house, maybe around 3 o'clock in the morning, we hear him jump in the shower," John explained.

At around 4 a.m., now Wednesday, John saw Robert leave and noticed Zuzu’s car was still there.

A few hours later John saw Robert’s mattress cover and clothes in the washing machine and Zuzu’s car hadn’t moved.

Then there’s Chris -- suspect number two.

Phone records show that Robert called him twice at 3:15 a.m. that same morning.

Chris told investigators that he picked Robert up later at night around 9 p.m. from his sister’s house.

“We cruised around and we went back to his place, and just had you know, a few drinks, small chit chat, just normal,” said Chris in a previous interview with our partners Crime Watch Daily.

But before that they made a few stops according to the arrest affidavit.

The first was Guzzi Up for drinks.

Then at 10:15 p.m. they pulled into Dollar General where Robert used Chris’ credit card to buy three plastic painter’s drop cloths.

Their next stop, Robert’s sister’s house.

Documents show that Jocelin Carrillo woke her husband up to ask if Robert could borrow his truck and he said yes.

Chris left Robert’s house around midnight, but he didn’t go straight home.

Documents show he stopped at several commercial dumpsters in town.

Then, at 12:30 a.m. he showed up to his friend Brittney Gasca’s house and doesn’t leave until 2:45 a.m. -- now Thursday morning.

Brittney told investigators Chris looked bothered and was acting strange.

She even told Chris he was scaring her to which he replied, “I don’t want to get you involved, don’t ask questions.”

She then asked if it was newsworthy, and he shrugged his shoulders and said, “If it’s

newsworthy I didn’t do anything, I’m okay.”

Friday October 14th, the day Zuzu is officially reported missing.

Robert visits his friend Josh Cobos, but didn’t mention anything about Zuzu’s disappearance.

Josh thought that was strange, but what really concerned him was the following comment from Robert:

“If I know a really big secret and two people know it, then the other has to be dead.”

Josh said Robert could tell he was worried and laughed it off saying it was a joke.

February 3rd, Zuzu’s remains are found wrapped in thin plastic sheets in a shallow grave off Wagon Road in Sunny Glen Canyon.

Those plastic sheets were consistent with the same plastic painter’s drop cloths that Robert bought at dollar general, according to the arrest affidavits.

The next day Robert was arrested for tampering with physical evidence by concealing a human corpse.

And just two days later on Monday, Chris is arrested and charged with the same crime.

“I want justice to the fullest extent and I want to make sure they are prosecuted to the fullest extent of the law,” said Zuzu’s brother Miles Verk.

Instead of flowers, the Verk family is requesting that gifts be made to a scholarship fund or to the Borderlands Research Institute. You can find that information here.
