15-year-old arrested on suspicion of murdering Fresno man in Pismo Beach

A 15-year-old boy suspected of murdering a Fresno man earlier this year is in custody after a months-long investigation, the Pismo Beach Police Department announced Thursday.

The incident happened near the Pismo Beach Pier promenade area at around 11:45 p.m. on Feb. 18 when the police department got several 911 calls regarding a shooting, according to a news release.

After arriving to the crime scene, police officers found 41-year-old Gustavo Aquino, of Fresno, with multiple gunshot wounds. He later died at Marian Regional Medical Center in Santa Maria, according to police.

During their investigation, police found that just before he was shot, Aquino had been approached by three males in the downtown area.

One of the males was identified by police as 19-year-old Daniel Jacob Santillana, while the other two were not identified because they are under 18 years old, according to police.

The three were believed to be associated with a criminal street gang in Hanford, police wrote in the news release.

Santillana, the two boys and Aquino got into a verbal altercation, during which one of the unidentified boys went to their car and took out a firearm, the release said.

The 15-year-old boy then shot at Aquino three times, police said.

Santillana and the two boys then fled the area in a car along with 19-year-old Anthony Robert Hernandez, of Delano, and two unidentified girls, according to police. The car was driven by Hernandez, police said in the release.

Pismo Beach police partnered with San Luis Obispo County District Attorney’s Office investigators, Kings County Major Crimes Unit, Hanford Police Department, Lemoore Police Department, Delano Police Department and Kern County District Attorney’s Office investigators to serve about 30 search warrants and investigate the incident.
