15-Year-Old Boy's MoVal Killing: Accused To Stand Trial On Murder

MORENO VALLEY, CA — A young man accused of gunning down a 15-year-old Moreno Valley boy during a robbery was ordered Tuesday to stand trial on a murder charge.

Terrence Vincent Young, 20, of Moreno Valley was arrested in December following a Riverside County Sheriff's Department investigation into the slaying of Gregory Shallowhorn Jr.

At the end of a preliminary hearing Tuesday at the Riverside Hall of Justice, Superior Court Judge Charles Rogers found there was sufficient evidence to warrant a trial on the murder count, along with a special circumstance allegation of killing during the commission of a robbery and sentence-enhancing gun and great bodily injury allegations.

The judge scheduled a post-preliminary hearing arraignment for Dec. 1 and ordered that the defendant remain held without bail at the Robert Presley Jail.

According to sheriff's Sgt. Ben Ramirez, the shooting happened just after 5 p.m. Dec. 6, 2022, in the 14600 block of Cagney Court, near Cactus Avenue.

Ramirez said patrol deputies were called to the location to investigate reports of a firearm assault and found Shallowhorn suffering from several gunshot wounds.

Paramedics attempted life-saving measures, but the youth was pronounced dead at the scene.

Ramirez said the defendant fled. However, in the ensuing days, Central Homicide Unit detectives were able to gather sufficient evidence pointing to Young as the alleged assailant, and a warrant for his arrest was obtained and served in the city of Bellflower, where he was taken into custody without incident in the predawn hours of Dec 9.

It was unknown whether the defendant and victim knew one another.

Young has no documented prior adult felony convictions in Riverside County.
