"Is that inconsistent with the defendant's statement he spread the arms out?" de la Rionda asked.
"That position, yes it is," Serino said.
But under cross examination, Serino said Zimmerman's description of Martin's body position was consistent with the medical examiner's report.
Later, in response to Serino's cross-examination testimony that he'd seen a convenience store video that showed Martin in a hooded sweatshirt, de la Rionda asked, "Are you saying in Seminole County, it's illegal for someone to wear a hoodie at night?"
"No sir. I'm not," Serino said.
It was Serino's second day on the witness stand. He and another investigator, Doris Singleton, testified Monday about their investigation as jurors heard a series of police interviews in which the detectives grew more pointed in their questioning.
In an early interview, just hours after the Feb. 26, 2012, shooting, Singleton recounted that Zimmerman noticed a cross she was wearing and said: "In Catholic religion, it's always wrong to kill someone."
Singleton said she responded, "If what you're telling me is true, I don't think that what God meant was that you couldn't save your own life."
But in an interview days later, Singleton and Serino suggest that Zimmerman was running after Martin before the confrontation. They also ask Zimmerman why he didn't explain to Martin why he was following him. The officers insinuate that Martin may have been "creeped out" by being followed.
"Do you think he was scared?" Singleton asked Zimmerman in one video interview.
Under cross-examination, though, Serino said Zimmerman seemed straightforward in his answers and didn't show any anger when talking about Martin. Serino said the increasingly pointed questioning is a tactic known as a "challenge interview," where detectives try to break someone's story to make sure they're telling the truth.
