New details reveal what DNA evidence investigators had when charging Chris Estrada with tampering with evidence following the murder of Zuzu Verk.

We also now know the rules of his bond release.

On October 12, 2016, the small town of Alpine was forever changed.

Zuzu, a student at Sul Ross State University, went missing.

Fast forward almost four months, devastating news broke -- her body was found in a shallow grave right outside of town.

Now her ex-boyfriend Robert Fabian and his best friend Chris Estrada are facing charges in relation to her death.

Both men remain behind bars at the Brewster County Jail -- Robert charged with murder and Estrada with tampering with physical evidence/corpse.

On Wednesday, Estrada and his attorney Jim Darnell went before a judge asking that his bond of $500,000 be reduced to $50,000.

During the hearing Darnell insisted that Estrada wouldn't be a flight risk and has cooperated with investigators from the beginning and will continue to do so.

However, Prosecutor and Assistant Attorney General Geoff Barr disagreed, saying Estrada is a safety risk to the community.

"We found later in the investigation a hair that was found in Chris Estrada's car," Barr stated in a sworn testimony. "Mitochondrial DNA is consistent -- analysis is consistent with that as being the same maternal line as Zuzu's mother. So right now it's not looking good evidentiary wise for Mr. Estrada and his participation in the context of the crime."

In the end the judge set Estrada's bond at $225,000.

Now the question is if he will be able to post that bond.

During his bond reduction hearing it was brought up that Estrada has a home in Marathon worth $100,000 and a 2016 Mustang worth over $40,000.

According to sources, Estrada saw a bondsman Wednesday.

His attorney said they are currently working to post Estrada's bond.

If Estrada were to make his bail, he would have some restriction to abide by.

The judge ordered him to reside within the counties between El Paso and Pecos County.

During the hearing Darnell mentioned that Estrada would most likely stay with a friend in El Paso, because his family lives in Tucson, Arizona.

He would also be required to wear an ankle monitor at all times and check in by phone with the Adult Probation Office every other Friday.

Darnell said they plan to plead not guilty.
