Family and friends held a vigil on Monday for a Riverside 18-year-old who was shot and killed in the parking lot of Central Community Church.
Luis Quintanar was shot after confronting a man during a walk with friends in the 5600 block of Arlington Avenue, Riverside Police Department officials said in a news release.
One of Quintanar's best friends, who was a witness to the shooting, said the teen was trying to calm the shooter down when he was shot.
"Luis turned around and said 'aye man relax dog, relax dude we ain't doing nothing.' He told him to relax and that's when he pulled out the gun and shot in the air," said the best friend. "We said 'relax' and walked up to him. As soon as he walked up to him, he just shot straight in the chest."
Quintanar was taken to a hospital where he eventually died. The gunman fled the scene after the shooting, according to police.
Family remembered Quintanar as a popular teenager with a big smile and warm spirit.
"He was just a guy with a big heart and always looked out for everyone," said Quintanar's older sister. "He looked out for everyone, he would always say he would take a bullet for his friends or family, and that's exactly what he did."
"It hurt waking up knowing that he's gone," said Kelly Zamora, a friend.
Quintanar was the youngest of three children and celebrated his 18th birthday on Aug. 18.
"If somebody knows something out there, you know, we want justice for my brother. They took our baby away," said Quintanar's sister.
The shooter is described as a bald, thin man. Anyone with information is asked to call Detective Mike O'Boyle at 951-353-7213 or Detective Dan Smith at 951-353-7103.
