Alex Trebek Injured Chasing Crook

Alex Trebek was put in "Jeopardy" when he chased down a thief at his hotel in San Francisco.  He is now on crutches after the ordeal.

Trebek, who just turned 71 this month, caught her stealing cash and a bracelet from his mother, which he had worn on the show every single day for 20 years. He also injured his other foot when he fell. The woman was taken into custody by San Francisco police and booked on felony burglary and possession of stolen property.
