Mammoth Lakes California

Mammoth Lakes, California has recorded 82 homicides over the tracked period, with 102 victims identified. Tracking continues through 2026. The city ranks #29 among 339 U.S. cities tracked by the FBI, with a clearance rate of 18% — meaning an arrest or suspect identification was made in 15 of those incidents, while 34 remain open. The weapon mix skews toward firearm - handguns (roughly 44% of cases with weapon data), with firearm - type unknown, knife/cutting instrument as the next-most-frequent categories. The single deadliest month on record was September 2022, with 13 homicides logged. Reporting is dominated by Mammoth Lakes Police Department, which filed 82 incident reports. The annual homicide count runs near the per-city average for the FBI's tracking universe. California's statewide firearms policy — an assault-weapons ban and universal background checks — is part of the regulatory backdrop for the local dynamic, even as the city-level pattern is shaped most directly by community-level conditions and the broader opioid and fentanyl crisis.
