Two brothers arrested Monday and charged with killing missing Moreno Valley teen Aranda Briones will be arraigned Friday morning, Feb. 15.

Owen Skyler Shover, 18, of Moreno Valley; and Gary Anthony Shover, 21, of Hesperia, will appear at the Hall of Justice in Riverside around 8:30 a.m. Friday, according to the Riverside County District Attorney’s Office.

The district attorney’s office said it filed a special circumstance that alleges the Shovers were lying-in-wait before killing Briones,16. A guilty verdict would make each eligible for the death penalty.

Both Shovers are in jail and ineligible for bail. Owen Shover is being held at the Robert Presley Detention Center in Riverside. Gary Shover is at the Larry D. Smith Correctional Facility in Banning.

Investigators have not found Aranda’s body, but they found evidence in one suspect’s backyard that led investigators to believe the girl was killed, according to the Riverside County Sheriff’s Department.

Briones and Owen Shover knew each other as acquaintances from Moreno Valley High, family members have said.

Sheriff’s officials said Briones never returned home Monday, Jan. 14, after a night out with friends.
