Testimony continues in the second week of the George Zimmerman trial in Sanford, Fla., as prosecutors look to make their case against him.
Monday, Chris Serino, the lead police detective who investigated Trayvon Martin's fatal shooting in February of last year returned to the witness stand.
He will be back up there Tuesday to discuss his investigation as the state hopes to establish that George Zimmerman is guilty of second-degree murder.
Jurors will hear a series of police interviews of detectives questioning Zimmerman, who claims he acted in self-defense, about his confrontation with Martin.
