Biehler's first recorded criminal offense dates back to February 25, 1956, when he and two accomplices, 22-year-old Louis Evangelisti and 18-year-old Kay G. Mills, broke into the home of Paul and Marguerite Troutner in
Pasadena during a robbery. After threatening to kill his wife if Troutner did not reveal where he hid his money, the trio tied them up with electric cords and gagged them with adhesive tape, before stealing money and valuables amounting to $1,500. A few months later, on December 22, Biehler went to the
North Hollywood home of a former associate, 38-year-old Julia Cook, who had an extensive criminal record for drug possession. As a result, Biehler was instead jailed for parole violation while Molin was later tried for unrelated offences, and despite the officers best efforts, they were unable to charge him with the killings at the time. After being paroled from prison in the early 1970s, Biehler again resumed with his criminal conduct, mainly centered around burglaries and pimping. On October 14, 1973, he confronted a retired paratrooper from
Sunland, 28-year-old Michael Rodney Coveny, after the pair had a scuffle at a lounge in
Shadow Hills for the latter missing the deadline for a $800 debt concerning cocaine. After driving him out to supposedly meet another supplier, Biehler threatened Coveny at gunpoint with a shotgun. Despite Coveny's pleas for mercy, he was shot and killed on the spot, and after his death, Biehler drove to the
Angeles National Forest, where he buried his body in a shallow grave. Sometime during that month, Biehler, disguised as a plumber, went to the pair's shared apartment in
Lake View Terrace, where he shot her four times in the head. Miraculously, Phillips survived, forcing Ellington to pay Biehler even more for a second attempt. He accepted, and
Christmas Eve, shortly after leaving a bar in North Hollywood, Biehler confronted Phillips, pressed the gun up to her face and fired two shots into her eye and then her ear. To make sure that she was dead, he fired two additional shots into the body before leaving the crime scene. ==Arrest and trial==
