UPDATE: Authorities have officially identified the body found in shallow grave as that of Zuzu Verk.

APLINE, TX – Police arrested the boyfriend of a missing college student, a day after human remains were discovered in a shallow grave near an area where the 22-year-old woman vanished in October.

Authorities took Robert Fabian, 26, into custody around 9 a.m. on Saturday. He is accused of tampering or fabricating physical evidence by concealing a human corpse, reports the Dallas Morning News.

Apline police said the remains, while not officially identified yet, have features consistent with missing student Zuzu Renee Verk.

Verk and Fabian were dating at the time she disappeared.

Fabian reported her missing on Oct. 14. Police said he was the last person to see her and was named a suspect in her disappearance. Authorities said Fabian stopped cooperating with their investigation.

Verk was enrolled at Sul Ross State University, where she studied conservation biology before she disappeared.
