Trayvon Martin's father testified Monday that he never denied it was his son's voice screaming for help on a 911 call, contradicting police officers' earlier testimony at George Zimmerman's second-degree murder trial.Tracy Martin said that he merely told officers he couldn't tell if it was his son after his first time listening to the call. Martin added that he concluded it was his son after listening to the call as many as 20 times. Several friends of George Zimmerman's testified Monday at his second-degree murder trial that he's the one screaming for help on a 911 call ?and not 17-year-old Trayvon Martin. Convincing the jury of whose voice is on the tapes is important to both sides because it would help them decide who was the aggressor in the confrontation that left Martin dead. Relatives of Martin's and Zimmerman's have offered conflicting opinions on previous days about who is heard screaming. Trayvon Martin's fatal shooting garnered worldwide attention when the man who fatally shot him wasn't arrested for weeks ? a backlash fueled largely by social media. Now, social media sites such as Twitter and Facebook have permeated George Zimmerman's trial both inside and outside the courtroom. A witness who testified via Skype was inundated with calls from other users on the Internet-based phone service, and a defense attorney was tripped up by a photo his daughter posted on Instagram. less
