Paul Holes is a scientist, seasoned investigator, and a true crime heartthrob, one who even has the capture of an alleged elusive serial killer behind his belt. But while it appears from the outside that Holes could have been dreamed up by a Hollywood screenwriter creating a role for the next gritty crime thriller, the retired Contra County investigator's contribution to criminal justice is no work of fiction. Holes is most famously credited with tracking down suspected Golden State Killer Joseph DeAngelo in 2018 after more than two decades spent hunting the man suspected of killing at least 13 people and committing more than 50 rapes throughout California. And after retiring in 2018, Holes has continued to lend his investigative skills to major cases across the country. Holes was part of the team that re-examined the mysterious death of Rebecca Zahau in Oxygen Media's "Death At The Mansion: Rebecca Zahau," which aired in summer 2019, and joined forces with journalist Billy Jensen for "The Murder Squad" podcast released earlier this year. During the podcast, the two investigators work closely with law enforcement agencies to take a fresh look at open cases, even asking for the public's help to solve the murders featured in the series.
