An initial theory of the murders centered around Holmes. After his left palm print was found at the crime scene on the Launius' headboard, Holmes was arrested and charged with four counts of murder in March 1982. The prosecutor, Los Angeles District Attorney Ron Coen, attempted to prove Holmes was a willing participant who betrayed the Wonderland Gang after not getting a full share of the loot from the Nash robbery. However, Holmes' court-appointed defense lawyers, Earl Hanson and Mitchell Egers, successfully presented Holmes as one of the victims, who had been forced by the real killers to give them entry to the house where the murders took place.
