PALO ALTO, CAAn email from Marison Octrup containing word of her husband's death was deleted by Eric Rawson's spam filter Monday, a review of the deleted-items folder would have indicated. "Dear extended Octrup family, it is with great sadness that I write to you to report the end of George's battle with emphysema. George died peacefully in his sleep on Sunday night," read the e-mail, which Rawson never received. "The funeral will be held at St. Francis' First Lutheran Church on Thursday, for those who might be able to attend." While the death notice did not reach Rawson, 14 offers for low-cost Cialis did.
