A man was taken into custody after he’s accused of shooting his brother to death inside a home in San Marcos Sunday evening, sheriff’s deputies said.

Deputies were called to the shooting just after 6 p.m. Sunday at the home in the 1300 block of Granite Road.

The suspect, identified as 45-year-old Fermin Olano, alerted deputies to the shooting. Multiple shots were fired and the suspect’s brother, identified by several neighbors as 46-year-old Fernando Olano, was found dead.

No one else was believed to be at the home at the time of the shooting, deputies said.

Neighbors said the brothers grew up at the home where the shooting took place and the family has lived there since 1976.

Fernando Olano was an electrician by trade and a musician at hear, neighbors said.

"This here is just shocking," said neighbor Harold Thyberg. "They were brothers. All brothers kind of fight, you know. Get into words. But this? I couldn't tell you. I have no idea how it happened."

Fermin Olano is being held in jail on suspicion of first-degree murder. He will be arraigned on Tuesday.

A motive wasn’t immediately clear. The official cause and manner of death will be determined by the medical examiner’s office.

Anyone with information about the shooting is asked to call the sheriff’s department’s homicide detail at 858-974-2321 or after hours at 858-565-5200.
