Two of the latest prosecution witnesses seemed to help George Zimmerman in his trial for killing Trayvon Martin in Sanford, Florida. An FBI audio voice expert testified today that under the conditions, it was impossible to determine the age of the male heard screaming for help on an audiotape. It appears there will be no forensic determination on this point. In addition, a police officer (Doris Singleton) who initially interviewed Zimmerman after the incident described his demeanor, which painted the defendant in a favorable light and understandably frustrated the prosecutors.
The officer who later interviewed Zimmerman and accompanied him on the "walk through" of the incident is on the stand now.
