A College art student who was known by friends as a "big, cuddly, teddy bear," and who was once convicted of killing his own grandmother, was sent to jail yesterday for writing "kill all women" on the classroom blackboard. Former Georgian College student David Welch, 29, of Richmond Hill, was sentenced in Barrie court to 90 days in jail, to be served intermittently so he can keep his job as a bouncer.
