Attempted murder suspect shot at Los Robles remains hospitalized

A Simi Valley man accused of attempted murder remained hospitalized in stable condition this week at Los Robles Regional Medical Center in Thousand Oaks — the same facility where a Simi Valley Police Department officer shot him on July 2, more than ten hours after a violent pre-dawn domestic incident sent both him and his wife to a trauma center, the Simi Valley Acorn reported Friday.

The case has set in motion parallel investigations by three separate agencies and has left the Simi Valley community with more questions than answers about what exactly unfolded inside a regional hospital room on a Thursday afternoon.

A Pre-Dawn Call on Clover Street

The chain of events began in the early hours of July 2, when Simi Valley police were dispatched just before 1:30 a.m. to the 2000 block of Clover Street on a report of "an unknown problem," according to SVPD Sgt. Rick Morton. What officers found when they arrived was far more serious: a husband and wife, both in their mid-40s, suffering from stab wounds.

Broadcasters and investigators who spoke with reporters in the days immediately following the incident provided additional details. KTLA reported that investigators believe the man attacked the woman first and then turned the violence on himself, and that four other people — including a child — were present in the home when the violence erupted. ABC7 reported that officers found two knives and a machete at the scene, with the machete recovered outside the home. Sgt. Morton told ABC7 that investigators were "still trying to determine exactly which item was used during the violence."

Both the husband and wife were transported by ambulance to what Morton described as "a local trauma center." Based on the investigation, 46-year-old Luis Santiago Ramirez-Macias was placed under arrest on suspicion of attempted murder, according to the Simi Valley Acorn. His wife underwent surgery and is expected to survive, ABC7 reported.

The Shooting Inside the Hospital

Ramirez-Macias was admitted to Los Robles Regional Medical Center in Thousand Oaks for continued treatment and evaluation, remaining throughout under what the SVPD described as "constant supervision" by one of its officers, the department said in a statement cited by the Simi Valley Acorn.

More than ten hours after the initial call, at approximately 12:20 p.m., NBC Los Angeles reported that the Ventura County Sheriff's Office responded to Los Robles after a shooting between Ramirez-Macias and the on-duty SVPD officer occurred on the fourth floor of a medical center building.

In its official statement, the Ventura County Sheriff's Office described a narrow sequence of events: the officer noticed Ramirez-Macias needed medical attention and summoned hospital staff to assess him; during that assessment, something happened that prompted the officer to fire. Ventura County Sheriff's Capt. Rob Yoos told reporters that it remained "unclear" what led the officer to open fire. No hospital staff, patients, or visitors were injured in the shooting, the Ventura County Sheriff's Office confirmed.

Within two hours of the shooting, Los Robles issued a public statement assuring the community that the hospital was operating normally, according to the Simi Valley Acorn. As of this week, Ramirez-Macias' wife also remained hospitalized in stable condition.

Three Agencies, Three Investigations

The layered jurisdictional picture is one reason why answers have come slowly. Thousand Oaks contracts policing services from the Ventura County Sheriff's Office, meaning the sheriff's agency — not the Thousand Oaks Police Department — holds primary investigative authority over the officer-involved shooting that occurred within city limits. The Ventura County Sheriff's Office confirmed its Major Crimes detectives are leading that investigation.

The Ventura County District Attorney's Office will also participate in reviewing the officer-involved shooting — standard practice in California under AB 1506, which mandates independent review of fatal and serious officer-involved shootings. Separately, the SVPD's Professional Standards Bureau will conduct its own internal administrative investigation into its officer's actions, the department said.

That means Simi Valley residents are waiting on three concurrent processes before any full public accounting emerges: the sheriff's criminal probe, the DA's independent review, and SVPD's own internal affairs inquiry.

What Remains Unknown — and Why It Matters

Key questions central to understanding the July 2 shooting remain unanswered. Officials have not publicly disclosed what medical condition prompted the officer to summon hospital staff, what specific actions occurred during the medical assessment that preceded the discharge of the firearm, whether Ramirez-Macias was physically restrained at the time, or how many shots were fired. Law enforcement officials said additional details are not being released to protect the integrity of the investigation.

For Simi Valley residents, the case intersects two deeply felt community concerns: domestic violence and police use of force. The incident also serves as a reminder of the procedural complexity that kicks in any time a Simi Valley officer takes action outside city limits — in this instance, inside a Ventura County-jurisdiction hospital roughly 12 miles from where the original call was made.

What Comes Next

The criminal case against Ramirez-Macias on the attempted murder charges stemming from the Clover Street stabbing remains active and separate from the officer-involved shooting investigation. As of press time, he remained hospitalized at Los Robles and had not been transferred to a custody facility.

Anyone with information about either the original assault or the subsequent hospital shooting is asked to contact the Simi Valley Police Department's Major Crimes Unit at 805-583-6950 or the Ventura County Sheriff's Office at 805-494-8200, the Simi Valley Acorn reported.
