Earlier Tuesday, prosecutors pushed to be able to introduce recordings of all the non-emergency calls Zimmerman made to police over an eight-year period. He called called the police close to 50 times to report such things as slow vehicles, loitering strangers in the neighborhood and open garages.
Prosecutors say that five of these calls could prove Zimmerman's state of mind on the night he shot the unarmed teen.
NBC News reports that a witness who tried to save wounded Martin also took the stand on Tuesday to recount what happened that night. Sgt. Anthony Raimondo of the Sanford, FL, police department told jurors how he arrived at the shooting scene, in the evening drizzle, on February 26, 2012, to find Zimmerman handcuffed by another officer.
