At approximately 11:25 p.m., both Officers Espadas and Roelofs entered the patio and handcuffed Mercado and checked him for additional weapons. Officer Roelofs checked Mercado’s carotid artery and stated, “He’s breathing still.” At approximately 11:28 p.m., SAPD Officer Mark Campi arrived and began administering first aid to Mercado and placed several occlusive dressings over Mercado’s wounds. Officer Campi requested additional medical supplies. SAPD Officer Luna arrived and provided supplies and dressed one of Mercado’s wounds and kept searching for other wounds. Officers Campi and Luna continued to treat Mercado on the ground in the patio area until paramedics (Fountain Valley Fire Department) arrived at approximately 11:36 p.m. Upon paramedic’s arrival, an examination revealed that Mercado had sustained several gunshot wounds to the upper buttocks and lower torso. His eyes were nonresponsive, he had no respirations, and no pulse. The automated external defibrillator (AED) was attached and confirmed Mercado was asystole. Mercado was ventilated and cardiopulmonary resuscitation (CPR) was initiated. An intravenous line (IV) was placed in Mercado’s left arm and he was given drip of normal saline and two (2) rounds of Epinephrine. Mercado regained cardiac activity with a pulse rate of 95 beats per minute and was placed in an ambulance. Once inside the ambulance, Mercado returned to asystole. Mercado was given two (2) more rounds of Epinephrine and transported, Code 3, to University of California Irvine Medical Center (UCIMC). Advance lifesaving protocols were continued while in transport. At approximately 12:15 a.m., Mercado arrived at UCIMC and was transferred to UCIMC Emergency Room (ER) where he was cared for by the treating physician. Mercado had no pulse and no respirations.
