Ms. O’Neal had recently called off her engagement to Lopez. Lopez confronted O’Neil in the parking lot and argued about her calling off the engagement. Lopez also demanded that O’Neil return the engagement ring. Ms. O’Neal was also in the company of a an acquaintance who attempted to intervene. At this time Lopez lifted his shirt and displayed a firearm. Ms. O’Neal’s friend immediately ran into the hospital to summon help and it was at this time Lopez drew his weapon and fired multiple rounds into Ms. O’Neal. Lopez then began to walk toward the Emergency Room entrance; at this time a squad car was entering the hospital’s parking lot. Lopez opened fire on the squad car causing the officers to perform an evasive maneuver. The officer’s then exited their squad car and gave chase of the offender into the emergency room waiting area. A gunfight ensued and a 10-1 was called over the radio. Officer Jimenez and his partner, Police Officer Armando Zambrano #19326, were working beat 231. They were assigned a station assignment and were en route to the 1st District police station when they monitored the call for a 10-1. Only a few blocks away they responded to the scene and joined the officers on scene in engaging Lopez inside the hospital. Inside the hospital’s lobby Lopez continued firing and would fire over 30 rounds during the incident. Unknowingly, Ms. Dayna Less, aged 25 years, a Pharmacy Technician was on an elevator approaching the 1st floor when the shooting inside the hospital was taking place. As she stepped out of the elevator Lopez turned his weapon on her and fired. Ms. Less sustained a fatal gunshot wound.
