It’s been hours since the tragic and horrific shooting at Mercy Hospital in Chicago. The shooting left three people dead, including a police officer that was responding to the gunfire. The shooting began around 3:30 P.M. yesterday after the gunman, Juan Lopez, confronted his ex-fiancée and emergency room doctor Tamara O’Neal, according to a local ABC affiliate. O’Neal was shot and killed in the hospital parking lot. Lopez then re-entered the building and killed pharmacy resident Dayna Less as she was walking out of an elevator. Officer Samuel Jimenez was responding to the call of shots fired when Lopez killed him in the lobby. Lopez was later found dead with a gunshot wound to the head. Another officer that responded to the shooting was struck as well, but saved by his firearm which stopped the round (via ABC 7 Chicago):


Officer Samuel Jimenez was one of three people killed by a gunman, who also died, police said.

The 28-year-old officer who ran into the line of fire to save others worked in the city's 2nd Police District and joined the department in 2017. Tuesday, he is being remembered as a husband and father of three young children.


Jimenez was shot and killed by the gunman inside the lobby of Mercy Hospital. He was responding to shots fired while he and his partner were on their way to a different call.

Police were called to Mercy Hospital at around 3:30 p.m. after a gunman confronted his ex-fiancee, emergency room doctor Tamara O'Neal.

The I-Team has identified the gunman as 32-year-old Juan Lopez. The couple's engagement was called off in September.


Lopez shot and killed O'Neal in the parking lot and then ran into the hospital continuing to shoot, killing a pharmacy resident coming off of an elevator who was just going about her business. She has been identified as 25-year- old Dayna Less.

We’ll have more details as they come public.
