CENTENNIAL, Colorado (CNN) -- A student opened fire Friday inside a suburban Denver high school, injuring at least three people before turning the gun on himself, authorities said.
The shooting began after the student entered Arapahoe High School in Centennial with the intention of confronting a teacher, Sheriff Grayson Robinson told reporters. The sheriff declined to identify the dead gunmen.
"I want to again repeat to you the suspect has been found inside the school and he has deceased as a result of what appears to be a self-inflicted gunshot wound," Robinson said.
At least one person -- a minor -- was taken to Littleton Adventist Hospital with a gunshot wound, Lauren Brendel, a hospital spokeswoman, told CNN.
Brendel did not release the age, gender and condition of the minor.
Two others were taken to Swedish Medical Center where they were reported in good condition, a hospital spokeswoman said.
The hospitals did not release the identities of the patients, but Robinson told reporters that two students were shot, including one who was taken to an area hospital in serious condition.
