A dead person was found near a vehicle that had been sought after a shooting at a Denver high school, officials in a nearby county said Wednesday night.

Park County officials did not identify the person found dead, but said the person was found near a vehicle connected to the suspect in the East High School shooting from earlier in the day.

Denver police named Austin Lyle, 17, as a suspect in the shooting that wounded two school administrators around 9:50 a.m., Denver police said.

The student was under a “safety plan” and had agreed to be patted down every morning, officials said.

“During that search, obviously a weapon was retrieved,” Denver Police Chief Ron Thomas said. “A handgun was retrieved, and several shots were fired.”

The weapon was not recovered at the school, police said earlier.

The vehicle he was driving was found in Park County, southwest of Denver, police said Wednesday evening. The SUV was found near Bailey, around 35 miles from the high school, Park County said.

Some residents in the area were told to shelter-in-place. The county said the order was lifted later Wednesday after the person was found dead.

One of the wounded administrators remained at a hospital in serious condition Wednesday night, while the other had been discharged in good condition, a spokesperson for Denver Health said.

Police said the student had never been found with a weapon prior to Wednesday morning’s incident. They did not say how long the student had been under the safety plan, which meant he was searched every morning in the school’s office, away from students and other staff.

Denver officials did not say why the student was under the safety plan, citing federal student privacy laws.

Safety plans are implemented throughout the district’s schools to address behavioral issues in coordination with a student’s guardians. Plans are tailored to individualized needs and put in place for minor issues to more severe concerns.

East High School recently lost a student, Luis Garcia, after he was shot and killed Feb. 13 while sitting in a car near the campus, NBC affiliate KUSA reported. The death of Garcia, a soccer player at the school, sparked a student-led campaign for gun safety reform.

Students led a walkout March 3 and went to the state Capitol to demand legislative action, according to KUSA.

Gracie Taub, the co-lead for East High School’s chapter of Students Demand Action, said in a statement tweeted from the organization’s account that this was the “reality” of American youth.

“This is the reality of being young in America: sitting through a shooting and waiting for information just hours before you’re scheduled to testify in support of gun safety bills,” Taub said.
