LOS ANGELES (AP) — Doctors have upgraded the condition of the alleged gunman in the deadly rampage at Los Angeles International Airport.

Ronald Reagan UCLA Medical Center in Los Angeles announced Tuesday that its last patient from the Nov. 1 attack has been upgraded from critical to fair.

Authorities sent 23-year-old Paul Ciancia there after police shot him four times during the confrontation at Terminal 3.

The announcement came on the same day that hundreds of people turned out for a public memorial service honoring Gerardo Hernandez, the first TSA officer killed in the line of duty.

Ciancia is charged with killing Hernandez and wounding three others, including two other TSA officers. Authorities say he targeted Transportation Security Administration employees.

The charges carry a potential death sentence.
