"This is the shoe I received," said Honolulu Police Department evidence specialist Toy Stech.
It was 3:25 a.m. on Nov. 5, 2011, when Stech said she got the call to go to the Queens Medical Center.
An hour earlier, 23-year-old Kollin Elderts was shot dead by Special Agent Christopher Deedy at the Waikiki McDonalds -- Deedy saying it was in self-defense.
Elderts' body was the first to arrive at the hospital.
Stech documented Elderts' bloody clothes and shoes before agent Deedy arrived with his clothes also covered in blood.
"This is the shirt I recovered from Mr. Deedy that morning," she told jurors, holding up a heavily-stained light green shirt in a plastic bag.
She documented his injuries too.
The pictures show a bump on his forehead, elbow, and several scrapes.
Stech was also tasked with testing for gun residue, not only on Deedy, but on Elderts as well.
"You have to think about holding a gun and where that hand would be touching," she said.
The last to arrive at the hospital was Deedy's friend Adam Gutowski, who jurors saw for the first time.
Gutowski also had bumps, bruises, and an injury to the head.
But then, she turned to the evidence on Deedy she didn't see, but smelled.
"I could smell it on his breath," she said, "and it's just from personal experience, you know, from being around people who have had a lot to drink, how you can just kind of smell that sour smell that's just coming out of your pores."
But Stech admitted she never mentioned any of that in her initial report, saying, it wasn't until detectives in the case called her months later, asking her to document that too.
"You did not give a written report about Deedy smelling of alcohol until a year later, until Jan. 14, 2012?" asked defense attorney Karl Blanke.
"That's correct," said Stech.
The prosecution also made sure to point out the matching blue marks on Deedy and his friend Gutowski's wrists, leaving the jurors to reach their own conclusions.
And it's still unclear as to whether Elderts might have tried to grab Deedy's gun at some point, hence the importance of where specialists found gun residue.
