dashed out to his brand new, coffee-colored Lincoln coupe and took off up New Utrecht Avenue, where a Buick sedan carrying four armed individuals stopped next to him. While Yale's new Lincoln was fashioned with armor plating, the dealer had neglected to bullet-proof the windows. Recognizing his peril, when the light changed, Yale took off. After a chase up New Utrecht, Yale swerved west onto 44th Street, with the Buick close behind. Yale's car was soon overtaken by the Buick, whose occupants opened fire at close range. A shotgun blast struck the Brooklyn gang boss on the left side of the head while a submachine gun bullet sliced through his brain. Either wound would have killed Yale instantly. The now out-of-control Lincoln veered to the right, hopped the curb, and crashed into the stoop of a brownstone at No. 923. This was the first time a submachine gun had been used in a gangland killing in New York City. On August 2, 1928, was reported that two men were sought for the murder of Yale.

Capone was said to give such belt buckles to those he admired very much. Police repeatedly questioned Capone about the Yale murder, but nothing came of the inquiries.

Most of these hitmen are believed to have participated in the St. Valentine's Day Massacre seven months later. One of the submachine guns used in the Massacre was later ballistically linked to Yale's murder. Yale received one of the most impressive gangland funerals in American history, at which thousands of
