Two deputies were shot and left in critical condition on Saturday in Compton, California, to surveillance footage from the Los Angeles County Sheriff's Department showed.
The search for the shooter, whom one of the deputies was only able to describe as a "dark-skinned male" is ongoing.
"He walked along the passenger side of the car," said Captain Kent Wegner. "He acted as if he was going to walk past the car. And then he made a left turn directly toward the car, raised a pistol and fired several rounds inside of the vehicle, striking both of the sheriff's deputies."
One of the deputies is a 31-year-old woman. She is married and has a 6-year-old son. The other deputy is a 24-year-old man. Both of them underwent surgery within four hours of the shooting.
L.A. County Sheriff's Department (LASD) reported a crowd of protesters "blocking the entrance & exit of the HOSPITAL EMERGENCY ROOM yelling 'We hope they die.'"
"They were saying, 'Death to the police,' 'Kill the police,' ... and they were using all types of curse words and derogatory terms about the police, just provoking our police officers," said a man interviewed by local ABC7 Eyewitness News. "Unacceptable behavior because the hospital should be a sanctuary where -- we should leave hospitals alone."
The man also confirmed that "the protesters tried to get inside the emergency room."
"This was an unprovoked, cowardly act," said Assembly member Reggie Jones Sawyer, who represents California's 59th Assembly District. "The individual will be caught, and justice will prevail. ... [W]e as a community, must condemn the actions of the perpetrators."
President Trump tweeted about the attack, saying, "If [the officers] die, fast trial death penalty for the killer. Only way to stop this!"
