SEE RELATED UPDATE: Attorneys dispute facts after new details, videos released following Riverside County in-custody death

JURUPA VALLEY, Calif, — Authorities say a man who fought first with a security guard and then deputies – nearly managing to remove the security guard’s firearm in the process – stopped breathing after being taken into custody Tuesday evening, Dec. 15.

Although paramedics were able to render aid and obtain a pulse before transporting him to an area hospital, the man’s condition later deteriorated and he passed away, according to the Riverside County Sheriff’s Department.

Deputies responded to Stater Bros on the 5500 block of Mission Boulevard just before 8:30 p.m., after receiving reports of an assault with a deadly weapon, Riverside County Sheriff’s Sergeant Lionel Murphy has since said of the fatal encounter.

When deputies arrived at the scene they saw the suspect, later identified as Ernie Serrano, 33, of Jurupa Valley, still inside the store and fighting with the security guard.

“While detaining Serrano, he continued fighting with the deputies and did not comply with their commands,” Murphey explained.

“At that time, a use of force occurred,” the Sergeant said; adding, “After Serrano was taken into custody, deputies noticed that he appeared to have stopped breathing.”

“Medical personnel on scene rendered aid,” according to Murphy who said paramedics were “able to obtain a pulse,” before transporting him to a local hospital for medical treatment.

“While at the hospital, Serrano’s condition deteriorated, and he was later pronounced deceased,” Murphy reported.

Although the Sergeant did not specify the type of force deputies used during Serrano’s apprehension, there are various types of force authorized by the department; which can include, but are not limited to, the use of control holds or impact weapons, as well as pepper spray or Taser deployment.

Citing the early and ongoing nature of the investigation, Murphy also did not specify if alcohol or drug intoxication or the possibility of excited delirium could have been contributing factors in Serrano’s death. 

Excited delirium – usually drug induced – can cause extremely irrational and delusional behavior, aggressive violence and unexpected strength. It can also cause very high body temperature and a dramatic increase in blood pressure and the condition has been cited as the primary or contributing cause of death in countless cases across the nation.
