Son of Omaha Police Detective Kills Assistant Principal, Self Vice principal killed, Omaha student kills self in high school shooting rampage.

Jan. 5, 2011 -- A high school student who was the son of a police detective shot two school officials at Millard South High School in Omaha today and then shot himself, police said.

The shooter was identified as Robert Butler Jr., son of Omaha Police Det. Robert Butler. He was a senior at the school.

Assistant principal Vicki Kaspar died Wednesday evening, as the result of her wounds, according to Omaha police. The principal, Curtis Case, is in stable but serious condition at Creighton University Hospital, according to the hospital.

According to a statement by police, Butler's father, a 7-year veteran of the department, was being interviewed, to try to get some insight into what prompted the incident.

Students rushed into the school's kitchen when the gunman opened fire. Sixteen-year-old Laura Olson, a junior at Millard, said she was just beginning lunch when the principal rushed into the cafeteria.

"He was like yelling, 'Get in the kitchen! Get in the kitchen!' He was waving his arms. You knew something was wrong and it wasn't a drill," Olson told The Associated Press.

Butler's body was found in a red Honda about a mile from the school. Police said he died of a self-inflicted gunshot wound.

He had recently transferred to Millard South from a school in Lincoln, Neb. Before the shootings, he posted an update to his Facebook page that read:

"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."

No other students were wounded during the shooting.

The first calls to 911 came from the school at about 12:50 p.m. and indicated that four to five shots had been fired inside the school office.

Police immediately headed to the school and to an apartment where the suspect was believed to live. They also learned that the suspect's mother might live in Lincoln, and advised the Nebraska State Patrol.

A SWAT team arrived at the school just before 1:15 p.m. and Butler's body was found in a parking lot about a mile from the school half an hour after the shooting, police said.

Parents began picking up their students shortly after 1:30 p.m., just to the west of the school. Other parents gathered at a church across Q Street from Millard South.

A recorded message from the school said that students are safe and police are in control of the school.

Other schools in the district were also dismissed.

The high school sits on the west side of Omaha, within city limits, and has about 2,100 students.
