She had suffered a severe head injury and was pronounced dead at hospital. DeJarnette was booked at the time for investigation of murder but was later released due to a of lack of evidence. The arrest comes after the authorities reopened the case in January 2012. DeJarnette joined the LAPD in 1982, working as a homicide detective and investigating rape cases.
