Authorities say one of the officers who has been hailed as a hero in the Fort Hood massacre has had a second surgery and is grateful for all the good wishes.

Sgt. Kimberly Munley was injured during the shooting rampage at the Texas post that she has been credited with helping end by shooting the alleged gunman.

Fort Hood spokesman Col. John Rossi read a statement on Munley's behalf at a news conference Saturday. He said she and her family were thankful for all the support and prayers that have some their way since the story of her actions emerged.

Rossi said she underwent her second surgery Saturday and is in good condition. She is most concerned that the wounded make a speedy recovery.

A doctor said earlier that Munley had a gunshot wound that had hit an artery.
