Alpine Police Chief Russell Scown also tells CBS 7 that a warrant for Robert Fabian was already in the works before a body was found Friday morning.
Everything we know so far: There have been several developments after a body was found outside of Alpine Friday morning.
At 10:00 a.m. Friday, the Brewster County Sheriff's Office was notified by a U.S. Border Patrol agent that human remains had been found in a shallow grave near Sunny Glen Canyon, northwest of Alpine.
The sheriff's office, Alpine Police Department, and Texas Rangers then responded to the location and established a perimeter.
According to BCSO, the remains appeared to be disturbed.
""It looks like an animal might have dug it up and scattered it about. Now we have to piece it all back together," Sheriff Ronny Dodson said during a phone interview.
A forensics team was called to the scene, and the plan became for the remains to be taken to the University of North Texas in order to both identify them and find additional evidence.
The Verk family then flew to Alpine and were picked up by members of the Alpine Police Department other than Zuzu's mother Lori, who was already living in Alpine temporarily.
In an interview with CBS 7, Lori stated she believed that the body was her daughter.
“It’s not over yet, not by a long shot,” Lori said with determination. “I want to find out exactly what, when, why, how, who -- that’s what I want to find out.”
Just before 10 a.m. Saturday, it was announced that the Alpine Police Department had arrested boyfriend Robert Fabian with a warrant for tampering with or fabricating physical evidence by concealing a human corpse.
Another release by the Alpine Police Department stated that evidence at the scene, including human remains, have features which are consistent with a match to Zuzu, though no formal identification had been made.
As of now, Fabian remains in custody at the Brewster County Jail.
