Michael Joseph Inderbieten was 21 when he was murdered on November 18, 1978, in Seal Beach, Orange County, California. Born December 29, 1956, in Long Beach, he was one of four children of John A. Inderbieten and Jean Marie Davis Inderbieten.

News coverage in late November 1978 reported his killing as part of a series of homicides in Southern California and later identified him as one of the victims of a serial killer. Early reports did not specify the method of killing or the precise location where his body was found. He was buried at All Souls Cemetery in Long Beach.

Michael’s death was investigated together with several related cases as authorities worked to link the pattern of killings and identify the perpetrator. If anyone has information about Michael, his movements in November 1978, or knew him personally, please come forward with tips.
