A 29-year-old Sacramento man has been arrested after an investigation into suspicious activity at schools in east Sacramento County led to the seizure of multiple firearms, law enforcement patches and tactical gear, the sheriff’s office said. The investigation of Dalmin Muran began after he was repeatedly observed engaging in suspicious activity at schools, according to the Sacramento County Sheriff’s Office. In one case, he allegedly drove his vehicle onto the grounds of Rosemont High School during the evening and was observed wearing military-style clothing and night-vision optics. After a security guard told him to leave, he allegedly said he should be allowed access because the schools are “public grounds.” The sheriff’s office said during other visits he erroneously claimed to have prior military service and expressed interest in joining law enforcement. Deputies executed a search warrant at a home last week in connection with Muran and found “numerous” guns that had been modified, including an unserialized “ghost gun” rifle hidden in an attic, the sheriff’s office said. Hundreds of firearm parts and components for building or altering weapons were also seized, along with multiple smoke grenades, flash bangs and “pepper spray deployable smoke grenades.” Deputies also found multiple law enforcement patches and tactical gear, “including those from the Sacramento County Sheriff’s Office.”Muran was released on bond hours after being booked into custody at the Sacramento County Main Jail, the sheriff’s office said.Muran faces four felony counts related to weapons offenses, according to a criminal complaint filed on Nov. 13. One of the counts alleges that he stole firearm accessories from a gun range. An earlier complaint filed on Dec. 11, 2024, accuses Muran of unlawfully carrying a concealed firearm. He was arraigned on that case in June. He is next due in court in connection with both cases on Jan. 14. The sheriff’s office said it is concerned there may be unreported incidents where Muran represented himself as a law enforcement agent.See more coverage of top California stories here | Download our app | Subscribe to our morning newsletter | Find us on YouTube here and subscribe to our channel
