Police: LAX shooting suspect is 23-year-old Paul Ciancia

                 LAX shooter Paul Ciancia on the floor after being shot by police.

This is the face of a madman.

A blood-drenched Paul Ciancia lays stunned on the floor at Los Angeles International Airport after brave airport cops shot him four times, including once in the face, to stop his rampage through the crowded terminal that left one TSA agent dead and six other people hurt on Friday.

Ciancia allegedly had a grudge against the Transportation Security Administration and a hatred for former Homeland Security chief Janet Napolitano, according to the Southern Poverty Law Center.

“FU Janet Napolitano,” he apparently says in the one-page, handwritten screed, in which he proclaims that airport searches violate his rights.

In this stunning first image of the alleged shooter, Ciancia is seen with his hands cuffed behind his slim body, surrounded by law enforcement as he stares off into space, next to a thick, bright pool of his own blood on the floor.

The shot he took to the mouth knocked out teeth and split his tongue, sources said. Ciancia, a Pennsville, NJ, native, is in critical condition at UCLA Medical Center.

He walked into Terminal 3, whipped out a semi-automatic rifle and began firing away at every Transportation Security Administration employees.

TSA Agent Gerardo I. Hernandez, 39, was killed and hundreds of terrified air travelers ran for safety as Ciancia stalked his way through the terminal.

His handwritten note also said he “wanted to kill TSA and pigs,” according to reports.
