Whether you are a football fan or not, you probably have heard the tragic story of Kansas City Chiefs' player Jovan Belcher, who recently killed his girlfriend Kasandra Perkins (who is the mother of his baby) before committing suicide in front of his coach and a few others in the stadium's parking lot. No one seems to know if Belcher had a history of violence in his relationship. But everyone has admitted that his girlfriend and him were having serious problems and had even broken up and gotten back together recently. In addition, Belcher had recently had trauma to the head and was on painkillers for it. We can't be certain of what actually happened, even if we listen to the horrible 911 call recording or watch video of police officers questioning Belcher hours before the murder/suicide, both of which are now all over the Internet. But we can take it upon ourselves to learn the signs of domestic violence and protect ourselves and those we love by sharing the info and acting when we have to. Recently, relationship therapist Bonnie Eaker Weil wrote about this on the SFGate site. While I don't know if I agree with Weil's assessment that relationships can overcome domestic violence (I have yet to hear of this happening), I do think we should use this terrible tragedy as a learning experience.
