The Los Angeles County Sheriff's Department is investigating the deaths of one former and three current employees reported over a 24-hour period this week, all believed to be deaths by suicide.
Homicide detectives responded to the first death around 10:30 a.m. Monday in Valencia, California, the department said in a statement to USA TODAY. Detectives were then called to a second death in Lancaster, California, just before 1 p.m. and a third in Stevenson Ranch, California, at 5:40 p.m., the statement said. Detectives responded to the fourth death at 7:30 a.m. Tuesday in Pomona, California.
The department did not identify the employees or respond to questions from USA TODAY about the manner of their deaths.
However, the Los Angeles County Department of Medical Examiner identified three of the deceased and listed the cause of death as suicide. The department said information about the fourth will be available after they have been identified and next of kin notified. The Los Angeles Times and NBC News reported all four are believed to be suicides.
