PRESS RELEASE: Out of State Arrest Made in January 14th Homicide Investigation

Turlock, CA – On March 23, 2023, an arrest warrant was issued in Stanislaus County after Turlock Police Department Detectives identified 22-year-old Gary Harold Jackson Jr. as the suspect in the shooting death of 21-year-old Romeo Xavier Portillo. The shooting occurred during the early morning hours of January 14, 2023, in Downtown Turlock.

On March 28, 2023, Turlock Police Detectives were contacted by Cobb County Police Department in Georgia and advised they had arrested Jackson for the homicide warrant obtained by the Turlock Police Department

According to Cobb County Police Department Officials, Jackson entered their police headquarters to apply for an alcohol permit. During a criminal history check, they learned of Jackson’s warrant. Officers with their Violent Crime Bureau were notified and Jackson was taken into custody minutes later, without incident.

Turlock Police Detectives are actively working with Cobb County Sheriff’s Office to extradite Jackson back to Stanislaus County where he will face homicide and attempted homicide charges.
