PANAMA CITY, Fla. (AP) - The widow of the gunman who held a Florida school board at gunpoint and fired shots before killing himself says she still doesn't know what triggered the shooting.

Rebecca Duke told CBS' "The Early Show" she'll spend the rest of her life wondering what made her husband, Clay Duke, interrupt a school board meeting in Panama City and eventually begin shooting at school board members.

In the interview broadcast Thursday, Rebecca Duke remembered her husband as gentle and compassionate man who had a good sense of humor.

Rebecca Duke also said she felt for the people at the school board meeting and for Mike Jones, the security guard who shot and wounded Clay Duke before he turned the gun on himself.
