OMAHA, Neb – The son of a police detective shot and wounded the principal and assistant principal of his high school on Wednesday, then shot himself in his car a few blocks away, authorities said.
Robert Butler, Jr., 17, who transferred in November to Millard South High school, left a suicide note on the social media site that said the school "drove me to this."
"Everybody that used to know me I'm sry but Omaha changed me and (expletive) me up. and the school I attend is even worse ur gonna here about the evil (expletive) I did but that (expletive) school drove me to this. I wont u guys to remember me for who I was b4 this ik. I greatly affected the lives of the families ruined but I'm sorry. goodbye," Butler posted on his Facebook page.
Butler had been suspended from the school on Wednesday morning, when classes resumed after the winter break, for using his vehicle to tear up the football field, local media reported.
Butler's motive was under investigation, Omaha Police Chief Alex Hayes told reporters, but his father was a police detective, which gave the son access to firearms.
"Tragedy has hit the Omaha Police Department as the suspect's father is an Omaha Police detective," Hayes said. "We are talking to him."
The principal, Curtis Case, was in stable but serious condition at Creighton University Medical Center, according to spokeswoman Kelsey Archer. He had been at the school for five or six years, Millard Schools Superintendent Keith Lutz said.
Assistant principal Vicki Caspar was in critical condition. She was a veteran administrator at the school, Lutz said.
The school was equipped with security cameras and guards and performed safety drills, Lutz said. "But nothing prepares you," he said.
