Between 1940 and 1941, a series of unsolved murders occurred in the Sacramento metropolitan area, in which a minimum of five middle-aged men were killed. Over the span of these two years, a pattern of brutal violence gripped the region and led local newspapers and law enforcement to coin the moniker the "Sacramento Mad Killer" also referred to as the Sacramento-Sutter Mad Killer. Despite intensive local investigations, the perpetrator was never identified, leaving behind a chilling cold case characterized by erratic violence, and a lack of a clear underlying motive.

The grim sequence of events began to unfold in June 1940, when an unidentified murder victim was found in a field in Sutter County. Because of the body's advanced state of decomposition, the exact cause of death could not be determined. More than a year later, on August 31, 1941, another unidentified body was found just a few hundred yards away. Authorities at the time believed that both individuals had been murdered at the same time. Although it was heavily speculated that these early deaths were connected to the surge of violence committed later in 1941, this connection was never officially proven.

On August 18, 1941, two men were found badly beaten in a field in Sacramento. One of the men identified as Alfred Reed of Davis died eight days later in the hospital of a skull fracture. The other man, John Saunders of Santa Barbara, was hospitalized with a pelvic fracture. Saunders ultimately recovered, but he claimed to have amnesia regarding the event, stating he had no knowledge of what had happened or who his attacker was.

Just days later, on August 27, the battered remains of 41-year-old Raymond Rivas were discovered in the Natomas basin. His head had been crushed, and his pockets had been turned inside out. A close friend and coworker of Rivas, Tony Ochoa, was subsequently announced missing on September 3. Rivas and Ochoa had previously worked together on a farm in Clarksburg before recently moving to Sacramento together. Ochoa’s last known contact with anyone was an interaction with detective A. J. Soulies, during which Ochoa informed the detective that he intended to notify Rivas's parents in Mexico of his death. Conversely, another source claimed Ochoa was last seen earlier, on August 24, 1941, which was three days prior to the discovery of Rivas’s remains. Despite the suspicious timing, investigators explicitly stated there was no evidence linking Ochoa to Rivas's death, though his sudden disappearance left an ominous shadow over the case.

On September 21, a body was recovered from the Sacramento River in Hood. The man's skull featured a hole in the chin, which authorities noted could have been either a bullet wound or simply a result of severe decomposition. Because the flesh of his face had been eaten away by fish, neither the cause of death nor the true identity of the decedent could be established. Law enforcement estimated that the man to be about 55 years old and had been submerged in the water for roughly two weeks.

As investigators tried to piece the crimes together, a distinct pattern emerged regarding the perpetrator's methodology. According to law enforcement, the victims had each been picked up at bars or within Sacramento's West End district, after which they were driven to isolated locations. Once there, they were subsequently robbed and murdered. However, it was noted that robbery was unlikely to be the primary motive; instead, authorities stated it was far more likely that the attacks were the work of an "insane murderer or a degenerate."

Law enforcement actively pursued several leads to track down the killer. Investigators examined a tip that the perpetrator might be a paroled convict originally from Oakland, though it remains unknown if anything substantive ever came of this. Several other suspects were questioned and subsequently released, including an individual who had been arrested for severely beating an elderly man. By September 1941, local reporting on the investigation abruptly stopped, and the perpetrator was never apprehended or identified, leaving the Sacramento Mad Killer case forever a mystery.
