May 7, 2024 – Michael Meiser, 39, was arrested April 30. Jail records show he was booked on suspicion of an unspecified felony on May 1. L.A. County Sheriff’s Department records show Meiser worked at North County Correctional Facility as an investigator. He worked with the jail’s anti-gang unit, known as Operation Safe Jails, according to two law enforcement sources who requested anonymity because they were not authorized to discuss the ongoing investigation. 

One of those sources and another law enforcement official, who also was not cleared to speak publicly about the case and requested anonymity, told The Times that Meiser was arrested for allegedly smuggling heroin into the jail complex in Castaic.

Jail records show Meiser was cited and released without bail last week. He did not immediately respond to an emailed request for comment on Tuesday and it was not clear if he has retained an attorney.
