A jury has begun deliberations in the murder trial of a Florida neighbourhood watchman who shot dead an unarmed black 17-year-old last year.
A prosecution rebuttal on Friday, prosecutor John Guy argued that Mr Zimmerman had repeatedly lied in his statements about the shooting.
"To the living, we owe respect," Mr Guy said. "But to the dead, we owe the truth. What do we owe Trayvon Martin?"
Mr Zimmerman could be acquitted, or convicted of second-degree murder or manslaughter.
