A 19-year-old Newhall man was arrested on suspicion of murder on a warrant on Tuesday afternoon, according to a spokesperson with the Santa Clarita Valley Sheriff’s Station.
No details on the incident for which Alejandro Trujillo was arrested were immediately available from the SCV Sheriff’s Station, the L.A. County Sheriff’s Department Information Bureau or the LASD Homicide Bureau.
According to Shirley Miller, a spokeswoman for the station, it was tied to a case that occurred in the SCV in 2025.
It would appear, then, that the arrest is connected to a shooting at a Halloween night party that left two men dead. That is the only murder case from 2025 in the SCV for which a suspect had not yet been identified, according to previous statements by detectives.
Trujillo was arrested at 2:15 p.m. Tuesday, but where exactly deputies located him was not available as of the publication of this story, Miller added.
According to LASD arrest logs, the 19-year-old is a kitchen worker and is being held in lieu of $2 million bail. The arresting agency was the LASD Community Partnerships Bureau, according to the arrest logs and Miller.
The SCV had four homicides in 2025.
On Halloween night, a shooting at a house party in Newhall claimed the lives of two men who were identified as Elijah Harts, a 30-year-old Encino man, who died at the scene, and 27-year-old Anthony Mora, a Newhall resident.
According to homicide detectives, the shooting stemmed from an altercation at the party.
Two male suspects were seen running away from the location in an unknown direction, according to an LASD Nixle alert published just hours after the incident.
Emily King, a California Institute of the Arts student, was murdered in her Newhall apartment on Feb. 4. Jack Minh Terry of Garden Grove was arrested on suspicion of murder for that case and is awaiting trial.
An 81-year-old man was taken into custody on suspicion of murder in September following the death of his wife, Penny Mortimer, who was 80 at the time.
Homicide detectives have previously said there were no known additional suspects in the murders of King or Mortimer.
