During cross-examination, the defense tried to have Osterman say the screams on the 911 calls were Zimmerman. Nelson said it was beyond the scope of the state's direct questioning.

At the start of court on Tuesday, the state sought to bolster or widen its already-granted motion preventing police from giving opinion testimony about the Zimmerman investigation. Judge Debra S. Nelson allowed Serino and Detective Doris Singleton to say they saw no evidence of ill-will, spite, or hatred in court on Monday--all of which are elements of second-degree murder.

De la Rionda introduced case law to the motion, which would limit what police can say about their interpretation of the law. The state wants Serino's opinion struck from the court record.

Serino said on Monday that Zimmerman was telling the truth or was a pathological liar. In cross-examination, defense attorney and former Local 6 legal analyst Mark O'Mara got Serino to exclude being a pathological liar, leaving the truth.

Nelson did say during testimony on Monday that the defense was coming close to violating the granted motion to exclude police opinion about self-defense.

The defense said cases that limit police opinion on veracity apply to authorities attacking the defendant and that Zimmerman's case involves authorities supporting Zimmerman. The cases the state is citing say veracity and credibility are "province of the jury" and allowing witnesses to offer such opinions cause reversible error.

O'Mara asked for time to research the case law. The state said it's also entitled to a fair trial and that the court has barred opinion testimony, so the jury should be asked to disregard improper comment of Serino.

Nelson ruled in favor of the state and asked the jury to disregard the testimony that Serino believed Zimmerman's story.

"That was an improper comment as to truth of veracity of another witness. You are asked to disregard question and answer," Nelson said.

Also before the jury entered the courtroom on Tuesday, the state said the defense failed to attend a Seminole State College witness testimony last week outside of court. Nelson allowed the witness, who taught an online course, to testify outside of court because of a scheduling issue.

The state said the defense's failure to attend the testimony is a waiver of defense's right to cross-examine the witness unless the witness is available on Wednesday.

Defense attorney Don West said it didn't become aware of significance of the witness' testimony, if any, until after the trial began.

Nelson tabled the issue for the time being.

Earlier on Tuesday, the state issued a motion for inquiry into a photo showing West and his daughters eating ice cream cones with the caption, "We beat stupidity celebration cones" that was apparently posted on Instagram the same day Rachel Jeantel testified in court.

West called the state "irresponsible" for filing the motion.

The 29-year-old Zimmerman has pleaded not guilty to second-degree murder. He claims he acted in self-defense.

Jurors on Monday heard a series of recorded police interviews of detectives questioning Zimmerman about his confrontation with Martin in a gated community in Sanford.
