Son Who Allegedly Attacked Dad With Machete Is Ordered To Stand Trial In RivCo

RIVERSIDE COUNTY, CA — A 21-year-old man accused of slashing an El Sobrante resident with a machete during a confrontation at the victim's home must stand trial for attempted murder and other charges, a judge ruled Tuesday.

Collin Adam Stewart of Riverside was arrested in April following a Riverside County Sheriff's Department investigation.

At the end of a preliminary hearing Tuesday, Superior Court Judge Emma Smith found there was sufficient evidence to bound Stewart over for trial on the attempted murder count, as well as mayhem and a sentence-enhancing allegation of inflicting great bodily injury with a deadly weapon.

The judge scheduled a post-preliminary hearing for Aug. 18 at the Riverside Hall of Justice. The defendant is being held in lieu of $1 million bail at the Smith Correctional Facility.

According to sheriff's Sgt. Patrick Montalvo, in the predawn hours of April 17, 2025, Stewart and the victim, whose identity was not disclosed, were involved in an unspecified dispute at the man's property in the 1600 block of Jordana Circle, near McAllister Parkway, in the unincorporated community situated between Lake Mathews and Riverside.

Montalvo alleged Stewart went after the man with a machete, inflicting several wounds. The victim was able to get to safety and call 911, at which point Stewart fled, the sergeant said.

He said patrol deputies and paramedics converged on the location within minutes and found the victim with non-life-threatening injuries. He was taken to a Riverside hospital for treatment and has since recovered.

Relying on the victim's statements and evidence collected at the scene, detectives obtained an arrest warrant for Stewart, who was taken into custody without incident late on the afternoon of April 17, 2025, near the intersection of McAllister and La Sierra Avenue.

A possible motive was not disclosed.

The defendant has no documented prior felony convictions in Riverside County.
