The Tim Bosma murder case will enter its final chapter next week after a four-month trial as the jury begins deliberating next week.

The judge in the case, Justice Andrew Goodman, is expected to begin charging the jury on Friday and deliberations will get underway next week.

Here is a look at six key pieces of evidence in the trial:

The Truck:

Tim Bosma’s truck, the same vehicle the Crown alleges Bosma was murdered in, was found in the MillardAir hangar at the Region of Waterloo International Airport two days after Bosma disappeared. The vehicle was discovered by an employee of MillardAir, who reported it to Crime Stoppers.

The Eliminator:

The Eliminator is an animal cremation device that was discovered on Millard’s farm in North Dumfries. The Crown alleges that the incinerator was used to burn the body of Tim Bosma. A forensic expert previously testified that the incinerator had been cleaned out but small bone fragments and two human bones were located inside.

The Letters:

While in custody, Dellen Millard, one of the two men accused of murdering Bosma, wrote to his former girlfriend Christina Noudga secretly. The letters were seized after she was arrested as an accessory after the fact in the murder. In one of the letters, Millard told his girlfriend that the killing was his co-accused Mark Smich’s “mess” and in another letter, he told her that the Crown’s case was “circumstantial and full of holes.” Another letter read that the two of them “need to get out stories straight. I need to know what you’re willing to do.” The letters give the jury a window into Millard’s thinking following the murder.

The Toolbox:

The toolbox was found in the possession of Smich after his co-accused Millard had been arrested in connection with the murder. The jury previously heard that Millard gave the toolbox to a friend who later passed it along to Smich. Smich testified that he was surprised when he found a gun inside the toolbox. While the murder weapon was never found, investigators did find the toolbox had traces of gunpowder on it.

The Gun:

The weapon used to kill Tim Bosma was never located but the Crown alleges that photo exhibits presented in court showed that both Millard and Smich had access to a gun. Smich previously told the court that he buried the gun but could not remember where. The gun in the photos seized from Millard’s computers also uses ammunition that matches a shell casing that was found inside Bosma’s truck

The Defence:

Lawyers for both men defended their clients by suggesting that it was the other who pulled the trigger. Ravin Pillay, the lawyer representing Millard, said there was no evidence that his client was planning anything more than a truck theft. Pillay said that it was Smich who pulled out a gun and shot Bosma when Bosma reached for the gun. Smich, on the other hand, testified that he was in fact following Millard in a separate vehicle when the shooting occurred and therefore couldn’t have shot Bosma.
