Blood Money - S19.E3

A boxing promoter is found strangled, and while Ross breaks the news to his widow, Burke and Reid interview the previous night's fighters. The winning boxer, Corbett, turns out to be more than good friends with the widow, and the ringside doctor has attempted to destroy medical files. An old friend of the promoters is also called in and soon more information is found which leads to a chase in order to prevent any further deaths.
