The notes showed that Bao changed his opinion on how long Martin could have been alive and whether the marijuana found in Martin's system was enough to affect him. Bao originally believed Martin could have been alive one to three minutes after he was shot, but he said he changed his opinion after a recent case that was similar to Martin's.
State rests case; Defense calls Zimmerman's mom to stand
After the prosecution rested its case shortly before 5 p.m. ET Friday, defense attorney Mark O'Mara argued for a judgment of acquittal, saying the State did not present enough direct evidence that Zimmerman did not act in self-defense. He also disputed the State's claim that Zimmerman acted with ill will, hatred or spite.
In his rebuttal, assistant state attorney Richard Mantei called Zimmerman a liar and pointed out inconsistencies in his version of events and the direct evidence presented in court. Judge Debra Nelson denied the defense motion, saying the decision is ultimately with the jury.
The defense started presenting its case, calling its first witness -- Gladys Zimmerman, the mother of George Zimmerman.
Gladys Zimmerman told jurors that it was her son's voice heard screaming for help in a 911 call. Zimmerman said she had heard her son scream, cry, play and yell in numerous situations over the years, which is how she was able to recognize his voice this time.
Jorge Mesa, Zimmerman's uncle, also took the stand Friday, claiming that was his nephew's voice heard on the 911 call.
Court is in recess until Monday.
