Volusia County assistant medical examiner Shiping Bao, whose testimony in the George Zimmerman murder trial was widely criticized, no longer works for the county, officials said.
Details about his employment were not released. Bao, who was hired with Volusia County in July 2011, made an annual salary of $175,950.
Bao received national attention during the murder trial of Zimmerman, who was acquitted on second-degree murder charges in the shooting death of Trayvon Martin.
Bao initially estimated that Martin lived from one to three minutes after Zimmerman shot him, but later testified that the Florida teen had lived up to 10 minutes. Bao said he had changed his opinion three weeks before the trial.
When questioned by Zimmerman's defense whether he had informed prosecutors about his new opinion, Bao said he had not.
