Same thing happened to actress Rebecca Schaeffer in '89. Some nut has been stalking her for three years, and used a private investigator to find where she lived (like the guy who attacked Saldana). He shows up the first time showing her the letter and autograph that she wrote him. Shaeffer told him not to show up again, so he went to a diner for breakfast. After he was done, he showed up at Shaeffer's home again, and shot her once in the chest. Sadly, she didn't survive from the shooting. I guess Shaeffer was also preparing for an audition for the Godfather Part III at the time.
