The suspected gunman in last week’s deadly attack at Los Angeles International Airport wrote a note saying he intended to die after killing at least one security officer, the chairman of the US House Committee on Homeland Security said yesterday.

Paul Anthony Ciancia, 23, also discussed weaknesses in airport security in the “suicide” note before Friday’s attack, Michael McCaul, the Republican congressman from Texas who chairs the committee, told CNN.

Ciancia is accused of fatally shooting a Transportation Security Administration officer, the first employee from the agency to die in the line of duty since it was created 12 years ago. Airport police shot and wounded the gunman, ending the rampage.

“It’s clearly one of those notes that reads, ‘I’m going to kill people and I don’t want to kill civilians,’ with the idea that he’s going to die at the end of this,” McCaul, who said he had read the note, told CNN.

He said the note “talks a lot about killing TSA agents, and he said, ‘If I just kill one, my mission is accomplished.’”
