Two suspects are in custody following the deadly school shooting at a charter school near Denver.
Police say 18-year-old Devon Erickson and a juvenile opened fire at the STEM school Highlands Ranch Tuesday just after lunch.
"When we were exiting the building, there was a trail of blood," said an unnamed student.
Investigators said the two shooters began firing in two separate locations.
An 18-year-old student was killed, and 8 others were injured. At least two students are still in serious condition.
Fernando Montoya told a local news station that his 17-year-old son was shot three times.
"A guy pulled I believe a pistol, I'm not sure, out of a guitar case, and start to shoot," he said.
The school, home to more than 1,800 students grades K through 12, was put on lockdown as police went on the hunt for the shooters who were both students at the school and not previously known to authorities.
"As officers were arriving at the school, they could still hear gunshots as they were entering the school," explained Undersheriff Holly Nicholson-Kluth of Douglas County.
The suspects, who were reportedly armed with a handgun and other weapons, confronted law enforcement officers when they arrived. Police struggled with them to take them into custody.
Details are emerging about the lives of the two suspects.
In May of 2014, Erickson expressed hatred for Christians on Facebook.
