Paul Ciancia, the gunman whose 2013 rampage at Los Angeles International Airport left a Transportation Security Administration officer dead and three others injured, has agreed to plead guilty to all pending federal charges, according to court papers filed Thursday.
Ciancia, now 26, will formally enter the guilty plea to 11 felony counts related to his Nov. 1, 2013, attack in the airport's bustling Terminal 3, including the murder of TSA Officer Gerardo I. Hernandez.
As part of the plea deal, prosecutors agreed not to seek the death penalty, but the murder charge to which Ciancia will plead carries a mandatory sentence of life in prison. The weapons charges carry another mandatory 60 years in prison, in addition to several years behind bars for other charges.
A federal judge will eventually determine the terms of his punishment.
Marshall McClain, director of the union that represents airport police officers, said he hoped the plea agreement would help Hernandez's family members heal.
"I'm an advocate for the death penalty. It's unfortunate that he took a life and still he's not going to be found guilty and put to death," McClain said. "If it helps bring some closure to the family, I'm all for it."
Former U.S. Atty. Gen. Eric H. Holder Jr. had made the initial decision to seek the death penalty — a rarely sought-after punishment for federal defendants. To justify capital punishment, prosecutors cited Ciancia's "substantial planning and premeditation."
That level of preparation by the New Jersey native was revealed in the plea agreement filed Thursday.
Ciancia, who had been living in Los Angeles for about 18 months before the shooting rampage, had purchased the Smith & Wesson semiautomatic rifle nearly seven months before he stormed into the terminal. To conceal his weapon, he tied two pieces of luggage together and fashioned a case, according to court papers.
On the morning of the attack, he asked a roommate to drive him to the airport for a trip back home to New Jersey, and while en route to LAX, he sent text messages to his siblings, with vague descriptions of his plans.
"I'm so sorry that I have to leave you pre-maturely, but it is for the greater good of humanity. This was the purpose I was brought here," he told his brother.
To his sister, Ciancia wrote that he had to "stand up to these tyrants." He asked his sister not to let the media distort his actions.
"There wasn't a terrorist attack on Nov 1. There was a pissed off patriot trying to water the tree of liberty," he wrote.
Ciancia's siblings grew concerned by the text messages and alerted police. Officers paid a visit to his apartment in Sun Valley, but U.S. Rep. Michael McCaul (R-Texas) later told reporters that police missed him "by a matter of minutes."
Inside the terminal, Ciancia removed his gun from a bag about 9:15 a.m. and aimed it at Hernandez, who was near a podium checking passengers' travel documents before travelers headed to an upper-level checkpoint, according to court papers. Hernandez, shot, fell to the floor and Ciancia proceeded up the stairs toward the TSA's security checkpoint.
About halfway up, he turned and saw Hernandez's body move. Ciancia walked down the upward-moving escalator, and at point-blank range, fired more rounds at him. Hernandez was shot 12 times in total, according to court papers.
After returning to the upper level, Ciancia spotted two other TSA officers and opened fire as they fled toward the gate area. Authorities said he continued along a corridor of shops and a third person, a teacher, was also injured. Meanwhile, passengers took cover, and as Ciancia walked he inquired if they worked with the TSA, witnesses told investigators. If they said no, he moved on.
About 9:25 a.m., he was shot and captured by airport police near a circular area of passenger-boarding gates. Authorities recovered a total of 500 rounds of ammunition that Ciancia brought to LAX.
Inside his luggage, investigators recovered a handwritten and signed note that mockingly said it was approved by Janet Napolitano, the former secretary of the U.S. Department of Homeland Security.
The note blasted the TSA for its "Nazi checkpoints" and the presumption that "every American is a terrorist." He said his mission would be a success if he killed just one TSA representative during his rampage.
In addition to disrupting travel for nearly 170,000 people, the deadly attack led to security reforms. Officials found the emergency response was hampered by poor communication and a lack of coordination among aviation and law enforcement agencies.
Ciancia, whose defense attorneys did not respond to requests for comment, was shot in the head and leg during a gun battle with airport police. He spent two weeks recovering at a hospital before he was transferred to a federal detention center in downtown Los Angeles, where he remains in custody.
