"But so does any pipe," Hamilton replied.
The first Glynn County police officer to arrive at the scene testified the 16-gauge shotgun recovered from the truck of Heinze Jr.'s car that appeared to have dried blood on it.
The defense argued that Lt. Keith Stalvey's testimony contained information not included in his incident report, and under cross examination admitted he couldn't be sure it was blood.
"No sir, I wasn't certain it was blood," Stalvey said.
On Wednesday, jurors heard the frantic 911 call in which Heinze said he had come home from a late night out and discovered the bodies. On the call he cried: "My whole family is dead! It looks like they've been beaten to death."
Prosecutors have told the jury it's significant that Heinze knew immediately how the victims had been killed. Glynn County police Lt. Keith Stalvey, who was the first officer on the scene, testified that the victims' head injuries were so grave that he at first thought they had been shot.
Heinze's defense attorneys say police rushed to build a case against Heinze and ignored other possible suspects. Defense attorney Hamilton also told jurors that police were ill-equipped to deal with such an overwhelming crime scene, with blood spattered on the floors and walls of a home already covered with trash and discarded clothing.
Hamilton pressed Stalvey on why he persisted in questioning Heinze at the scene when he was shaken after seeing the bodies and was under the influence of drugs. Heinze told police he had been smoking marijuana. Drug tests later showed crack cocaine and a prescription painkiller in his system.
"You have walked into the crime scene and seen blood covering the walls," Hamilton said to the police officer. "You wouldn't assume he was traumatized by that?"
"He may have been traumatized, but I was at a murder scene," replied Stalvey, who said Heinze was not a suspect at the time and wouldn't have been questioned if he had been because he was intoxicated. "And I was trying to the best I could and find out who did it."
