Elizabeth Clayton is a woman 40-50 y.o.a as of 2017. She had a daughter named Daisy who was murdered in 2009. After Daisy's death, Elizabeth became addicted to oxycodone. She was conscripted into a drug gang that used people such as herself to fill bogus prescriptions for oxycodone. The gang operated out of Pacoima and Slab City. In 2017 she met Harry Bosch who was working undercover on a murder investigation. When the drug gang was broken up, Bosch took her to the Road Saints clubhouse where she was kept in a locked room to get her past the initial phase of opioid withdrawal. Bosch then paid for her to get into rehab at a facility called The Start in Canoga Park.
