The incident unfolded outside his ex-girlfriend's home in the 2400 block of East 126th Street around 10 p.m.
Deputies say the man drove to the residence and found his ex-girlfriend and mother of his one-year-old son with another man. The suspect then shot the woman's boyfriend in the face with a revolver. The man then fled the scene with his son in the car.
Responding deputies shortly located the suspect's Honda Accord and attempted to conduct a traffic stop, but the armed suspect refused to yield. That's when a pursuit ensued.
The suspect eventually drove back to his ex-girlfriend's residence where he stopped his car in the middle of the street and used his son as a shield while exiting the vehicle. Officials say the man was holding his baby with one arm and holding a revolver in the other.
The man opened fire on deputies while holding the baby, but deputies did not return fire.
"He is walking down the middle of the street, while pointing the gun at the deputies," said Lt. John Corina, "the deputies, of course, aren't shooting at this person because he's got a baby."
The suspect then attempted to open the front door, but the front door was locked.
Neighbors in the area watched the scene unfold in horror.
"'Let go of the child!' They repeated that several times, he was using it, probably I don't know, to try and get away," said neighbor Edgar Ramirez.
The suspect's ex-girlfriend eventually managed to grab the child away from the suspect. That's when deputies say the suspect opened fire again, and a deputy-involved shooting ensued.
No deputies were injured. The child was not hurt.
The suspect was shot multiple times and remains hospitalized in critical condition, but is expected to survive. The woman's boyfriend was transported to a local hospital and is also expected to survive.
The suspect's handgun was recovered at the scene. His identity has not been released.
The sheriff's Internal Affairs Bureau and the District Attorney's Office are investigating the incident, which is typical protocol following deputy-involved shootings.
