Experts: Trayvon Martin's heart kept pumping after shooting
George Zimmerman may have shot Trayvon Martin in the heart, but that didn't kill him instantly.
The 17-year-old survived for several minutes, according to two experts who reviewed Trayvon's autopsy for the Orlando Sentinel.
"You're talking about minutes, at least, for him to survive," said Dr. William Anderson, a forensic specialist and former deputy medical examiner for Orange and Osceola counties. "I think he would have been conscious … for a little time anyway."
What killed the Miami Gardens teenager was blood loss, massive internal bleeding, said Anderson and Dr. William L. Manion, a board certified anatomical, clinical and forensic pathologist and lawyer in Mt. Holly, N.J.
During an interview March 24 with agents with the Florida Department of Law Enforcement, Livingston said: "He had a small bullet hole in his chest area that wasn't even bleeding,"
Not on the outside.
Inside, however, his chest cavity had filled with 2,300 milliliters of blood, according to the autopsy. That's about one-third of a healthy person's total blood volume, Anderson said
