According to the Associated Press' WILLIAM FOREMAN: "The Americans have been analyzing bullets, blood samples, medical photos and other evidence from the March 19 shooting that grazed Chen's stomach. The bullet hit Chen as he was campaigning in an open Jeep in the southern city of Tainan.
Some skeptics say it's highly suspicious that the bullet conveniently ended up in the president's jacket.
But a ballistics expert with the U.S. team, Michael G. Haag, told cable station TVBS that "it's not unheard of for bullets to be just about to pump out of somebody who's been shot, or out of their skin, and to be found in somebody's clothing.''
Doubters have also said that it was suspicious how one bullet pierced the Jeep's windshield and hit the vice president's knee. They say the bullet couldn't have followed such a trajectory.
But Haag told TVBS: "As soon as (the bullet) changes the medium that it's in, air to glass, air to wood, or air to water, then deflection ... occurs and the bullet's path can change.''
Some have said Chen's injury doesn't resemble a gunshot, because a bullet wouldn't leave such a long scar.
But another team member told TVBS that many factors could influence the wound's shape and size.
"That varies greatly depending on the nature of the ammunition, how close the wound is, what part of the body,'' said Dr. Cyril H. Wecht, a forensics expert who investigated Kennedy's assassination. "
