JACKSONVILLE, Fla. (AP) - Jacksonville police say a man shot his 11-year-old son and the boy's mother in a hospital parking garage before killing himself.

Jacksonville Sheriff's Office Chief Rick Graham said Thursday the woman was in critical condition, and the boy was in fair condition.

Graham said the shooting occurred about 5:30 p.m. as the three were walking toward the parking garage outside Baptist Medical Center. Nurses came outside after the shooting and began treating them. No one else was wounded.

Authorities said the couple had taken their son to Baptist on Wednesday night. The names of the man and the two victims have not been released. The cause of the shooting and whether the couple was married were unclear.

A hospital spokeswoman deferred comment to police.
