HACIENDA HEIGHTS – A teen remained on life support Tuesday after a shooting that left a 17-year-old boy dead. Demetrius Flores, 17, of Rowland Heights was killed Monday in a shooting in a wash near the 15600 block of Los Altos Drive, about a block from Los Altos Elementary School, shortly after 2 p.m. The surviving victim was taken to Los Angeles County-USC Medical Center. Sheriff’s deputies would not release the boy’s name, but said he was around 17. A juvenile suspect was in custody Tuesday, and two other suspects are being sought, said Sheriff’s Deputy Ban Nyugen. Detectives would not give details on what prompted the violence. Gary Harn, 18, a friend of the victim, visited the wash Monday. “I just had to see it,” Harn said. He said Flores had a twin brother, attended Los Altos High School and played football. “He was so young. I still can’t believe it.” Hacienda La Puente Unified School District officials would not confirm whether the boys were students at the district, but several students at Los Altos High School said both boys had attended their high school at one point. Students were upset Tuesday, said Precious Lopez, a sophomore. “People were crying” and one teacher prayed, said Lopez, who was saddened but not shocked. “It’s not a surprise that this would happen in the area,” she said. Counseling was available Tuesday for students at 10 schools in the vicinity of the shooting, said district spokeswoman LaDonna Jackson. The school district police responded first to the shooting, Jackson said. Los Altos Elementary, Newton Middle School, and a “Mommy and Me” class at the Instructional Service Center were placed on lockdown as sheriff’s deputies investigated the shooting; students at Los Altos Elementary were bused to Los Altos High School, where they were released to their parents. Parents of Newton Middle School students were allowed to take them home.
