Phillip Carl Jablonski, born on January 3, 1946, in Joshua Tree, California, led a life marked by extreme violence. After relationships marked by brutality, including acts of attempted strangulation and sexual violence, he was convicted in 1972 for the rape of an acquaintance. Subsequently, Jablonski committed a series of heinous murders, including that of Linda Kimball in 1978, his wife, whom he beat, stabbed, and strangled. After serving a twelve-year sentence for this murder, he murdered Carol Spadoni and her mother Eva Petersen in 1991, using particularly cruel methods such as shooting, suffocation with duct tape, and sexual assault.

Furthermore, Jablonski was accused of the brutal murder of Fathyma Vann in California, characterized by gruesome mutilations including the removal of eyes and ears, as well as the robbery and murder of Margie Rogers in Utah, where the victim was sexually assaulted and executed with two gunshot wounds to the head. His series of murders led to a death sentence in 1991. Despite his request for visits to ease his time in detention, Jablonski passed away in prison in 2019 at the age of 73.
