Many parents were glad to see extra security. Even though there's no specific threat reported, tensions are high.
"It's better for the police to be here, it's more protection for all the kids, nobody can get hurt," said Redlands resident Alma Gomez.
"I'm glad this is like this, but how long do you honestly think this is going to last? As soon as security eases up, I'm worried that my child is going to get hurt," said Redlands resident Rishon Sherman.
Sherman's daughter is a junior at Redlands High School. Like other parents, she can't believe the level of violence among teenagers.
It was last Wednesday night that 17-year-old Quinn McCaleb and 16-year-old Andrew Jackson were shot and killed. They were both students at Redlands High School.
"A fight should never be the reason why you die. I'm in my 30s. Growing up, when we got into a fight, you walked away with bumps and bruises. You still walked away breathing. Now these teenagers got guns, and they think that it's fun, they're a man because they can shoot a gun. I'm a female, I know how to shoot a weapon, but i'm not going to go around shooting innocent people," said Sherman.
Police released a composite sketch of the suspect.
Detectives are looking for two vehicles that might be involved in the shooting, a mid- to late-1990s dark green Honda. The second description is more vague: a dark-colored vehicle with shiny rims.
Meantime, counselors were also on hand at all three Redlands high schools to help students cope with the loss of close friends.
"This is really tough. My sister, she's been crying this whole entire time, and so I had to be strong for her," said Redlands student Courtney Sherman.
A prayer vigil for the victims was scheduled for 4 p.m. Tuesday at the scene of the shooting.
Anyone with information related to the incident was urged to call the Redlands Police Department at (909) 798-7681.
