After four months of testimony, the jury has finally heard allthe evidence in the murdertrial of the two men accused of killing Hamilton residentTim Bosmain 2013.

• Live at 9:30 a.m. Tuesday: Closing arguments begin

Smich, 28, of Oakville, Ont., and Millard, 30, of Torontohave both pleaded not guilty to first-degree murder.

Bosmavanished on May 6, 2013, after takingSmichand Millardon a test drive in a pickup truck he was trying to sell. Investigators later found charred human remains, believed to belong toBosma, in a livestock incinerator on the Millardfarm in Ayr, Ont.

Here's a look at 10 key exhibitsthat will playa role when jurors begin deliberations:

10. Millard's letters to ChristinaNoudga

While Millard was in jail, he managed to pass along letters to his girlfriend at the time, Christina Noudga, despite a court order that the two not communicate. He told her to destroy the letters, but she didn't, and they became part of the Crown's case.

The significance: AsMillard didn't testify,the letters fromjail represent the closest the jury got to learning something about his character and thinking. The letters do not contain a smoking gun per se, but do show how Millard planned to defend himself, and reveal his extensive attempts to try to co-ordinate statements and actions by potential witnesses from behind bars.

9.The Eliminator

The Eliminator is the brand name of a livestock incinerator found on Millard's farm in Ayr, Ont.

The significance: The incinerator is central to the Crown's theory that after Bosma wasshot and killed, his body was burned. The Crown presented evidence of Millard and his friends searching for and buying the unit,and talking about it during a series of texts. Among the group it was known as "the BBQ."

8. Cellphone records

A detailed and lengthy presentation outlined the movements of several cellphonesduring the day and evening Bosma disappeared. Their locationsweretracked by the cell towers they pinged off.

The significance: With this presentation, the Crown tried to connect the movements of Millard and Smich with those of the phone that had been used to callBosma to arrange the truck test drive. The jury was shown how the phone making the test drive arrangements moved in concert with the phones of Millardand Smichon the night of May 6. The Crown suggested this placed both men atBosma's home. Later in the trial, it was acknowledged that both were there.

7. The blood

Multiple exhibits were presented as a series of photographs. The Crown introduced a range of evidence showing traces of blood inside and outside Bosma's pickup truck.

The significance: The evidence was among the most graphic presented. It was used by the Crown to supportthe core of its case that Bosma was shot inside his own truck.The evidence demonstrated where Bosma was sitting, the jury was told. A blood spatter expert testified it was clear a "bloodletting" event had happened inside the truck and there was evidence of attempts to clean up the blood.

6. The bone fragments

Two bone fragments, about 10 cm and 20 cmlong, and a tooth were found inside The Eliminator incinerator.

The significance: They were the only identifiable pieces of remains found during the investigation. Though scientists tried various methods of identification through DNA and dental records, the bone shards and a piece of a toothfound in the incinerator were too damaged to conclusively identify the person linked to them. Presentation of the bone shards and tooth piecein court was among the most difficult moments for the family during the trial.

5. The toolbox

A toolbox, in which a single gunshot residue particle was found, was seized in connection with the case.

The significance:The toolbox evidence shows the movements of what is believed to be the murder weapon after Millard was arrested. Court heard that Millard gave the toolbox to friend Matt Hagerman,right before his arrest. Hagerman and another friend, Andrew Michalski, passed it on to Smich, along with a bag of marijuana. Smich testified he was surprised to get the gun and thought Millard might be trying to frame him.

4.The gun

The jury saw a series of pictures obtained during the investigationof a gun, aWaltherPPK.The Crown suggested it was likely the gun used to killBosma.

The significance: The pictures show Millard and Smichhad access to a gun. That's important because a murder weapon was never found.Smichsays he buried it and can't recall where. The gun also uses the ammunition that matches a shell casing found insideBosma'struck. Each accused pointed the finger at the other as the one who brought a gun to the test drive of Bosma's truck.

3. The hangarvideo

Security video seized from a business near theMillard Airhangar shows the arrival of a truck and a trailer. It also shows a flash of light believed to be the igniting of the incinerator hours afterBosmawas killed.

The significance: This video was also among the most chilling presented by the Crown. Does it show the moment thatBosma'sbody was being incinerated? Beyond that, it shows Millard and Smichmoving around the hangar in the early morning hours afterBosma'sdisappearance.

2.The gloves

When police arrestedMillard, they foundblacknitrilegloves in his possession. Inside those gloves,they found DNAthat with a very high degree of probability belonged to Millard, andDNAthat wassimilarly linked to Noudga. On the outside, they found blood stains, that again, with a high degree of probability containBosma'sDNA.

The significance: One of the many puzzle pieces that the Crown is using to try toplace Millard at the centre of the crime.The combination of likely DNA matches has Millard wearing the gloves that came into contact withBosma,or at leastBosma'sblood.

1. The truck in the hangar

The picture ofBosma'struck in theMillard Airhangar was taken by an employee, Arthur Jennings.He went to the police with his suspicions.

The significance: This represents a key break in the early stages of the investigation, further linking Millard to the probe (along with the cellphonerecords and his ambition tattoo). Jennings had seen news reports about Bosma'sdisappearance, saw the truck at his work a few days later and did what no one else with peripheral connections to the accused didhe contacted police. He took a photo and recorded the VIN number.His recounting of his thinking: "Oh my God, could that be the truck?" was one of the most dramatic moments of the trial.
