Noting that it began happening just a few days ago, local 31-year-old Anthony Forster told reporters Monday that his left knee has been making a really strange sound lately. Its like a little clicking noisecan you hear it? said Forster, as he repeatedly flexed his knee back and forth in an effort to demonstrate the unusual sound. You have to get really close and listen for it. It usually happens when I bend my knee all the way back andthere, did you hear that? It was doing it worse before, but you can still hear it. At press time, sources confirmed a small blood clot just above Forsters knee had broken loose and was traveling through his bloodstream to his brain, where it is expected to cause a massive stroke, killing him instantly.
