The threat at the University of Louisville ended with no injuries about half an hour after it began, but police who were then asked by school officials to check on the children found them dead with gunshot wounds.
Gail Lynn Coontz, 37, is charged with killing 14-year-old Greg Coontz and 10-year-old Nikki Coontz, said Louisville police Officer Phil Russell.
Gail Coontz was the armed student, said police Lt. Barry Wilkerson. She is in custody at the University of Louisville hospital but is expected to be transferred to jail, Russell said.
The woman was also charged with one count of terroristic threatening for pointing a handgun at an officer, said university police Maj. Kenny Brown. The woman gave her handgun to a counsellor at the health services building, he said.
"When we were able to open the door and go in, the student and the counsellor were both sitting on the couch," Brown said.
The children were shot sometime in the past day, Russell said, declining to say where their bodies were found in the house. He didn’t mention a motive.
Coontz has been a student in the college of arts and sciences since fall 2006 and had not declared a major, said university spokesman John Drees.
The school sent safety alerts to student phones and cellphones and posted one on its website. The campus was not locked down, university spokeswoman Cindy Hess said.
The two-storey red brick home where the children were found is in a tidy middle-class neighbourhood.
A garden at the home has a statue of two children playing with a bicycle. The neighbourhood is about 16
kilometres south of the university.
