Here is a great wrap-up and Timelinehttp://www.tmz.com/2007/02/08/anna-nicole-smith-collapses/#continuedcontents
Thanks for the link to TMZ (great celeb site). I read the timeline and found this peaking my couriosity...apparently in addition to hitting her head, she also had 'flu like symptoms' earlier this week. Ok, maybe legit. Or maybe some poisoning/drugging building it its effects. Keep in mind that the Larry Birkhead DNA testing was looming (at the end of February)...could that impending date have pushed Stern over the proverbial edge?
