On June 20, 1999, William and his wife Bianca was on the way to pick up Sofia, their 9 year old daughter at a daycare in the suburbs of Chicago, Illinois. When they arrived at the daycare, a black Honda Civic pulled up aside their Aston Martin. The unknown driver rolled up the windows and fired 10 shots which hit William twice in the neck. His wife rushed him to the nearest hospital where he died hours later.
