Bosma'skey was found on a ringattached to the key in the ignition of Millard's SUV a GMC Yukon.

Const. RyanTocher, who was working with the Hamilton police homicide unit in 2013, was tasked with tryingthekey inside the truck Bosma had been trying to sell online, he testified Tuesday.

"I went up through the bed and in through the driver's side window and it started,"Tochersaid.

Police also found a red duffel bag in the back of Millard's SUV. When they opened it, investigators found a receiptfor an incinerator registered to Millard Air fromJune 21, 2012.

With taxes, freight and extras included, the bill was for $15,424.50.

The Crown's opening address said thatbone fragments were found inside aportable incineratorused to dispose ofBosma'sbody. The incinerator was found on Millard's farm nearWaterloo, Ont.

A beige satchel was also found inside the SUV. The presence of a satchel has been noted at several points during the trial, but its significance has not yet been explored.

Defence grills police witness

Before that evidence was presented in the second half of the day, defence attorneys pressed a police witness about the wayBosma'struck was examined.

Testimony resumed in the morning with Det.Const. LauraMcLellanfromHaltonRegional Police explaining the multiple areas where blood was found inside and outside the truck.

Blood was found in the tread of the rear passenger side tire and on the handle of the glove box,McLellantestified. Blood was also found on the cushion of the back seat and on the roof liner above one of the visors.

Bosma'sfamily sat in the courtroom through that testimony.Bosma'sfather, Hank, put his arm around his wife, Mary, whileBosma'swidow,Sharlene, wiped away tears.

In cross-examination,Smich'slawyer,ThomasDungey, askedMcLellanwhy there wasn't video evidence of police conducting the forensic investigation, or photographs taken of certain portions of the investigation.

No video shot during examination

"You have an opportunity to show to this jury exactly where evidence was taken, and you don't take photos of it?"Dungeyasked, his voice rising. "Wouldn't it have been of assistance to the jury?"

"I could have, but I didn't,"McLellansaid,adding that in her experience, police document the evidence, not officers conducting the investigation."We don't generally do that," she said.

Dungeyalso centred a good portion of his cross-examination on the spent shell cartridge that was found in the back of the truck's cab.

Over the course of a few days early on in the investigation, the truck and its trailer weremoved from Millard's mother's hometo a trucking facility in Hamilton, and then to an Ontario Provincial Policefacility inTillsonburg, Ont., court has heard.

"The truck, having gone all these places, it's within reality that anything within the cab part could have rolled back,"Dungeysaid.

In his cross-examination, Millard's lawyerRavinPillaypressedMcLellanabout the factthe trailer had opened up on the highwaywhile in police custody on the way to the facility inTillsonburg.

"That was obviously a concern for you?"Pillayasked.

"It was a concern, but it was locked up by the time we got toTillsonburg,"McLellanresponded.

Mishap 'not a good thing,' witness says

Pillayalso asked if it's a "good thing" from a forensics standpoint for a trailer carrying important evidence to open up on the highway.

"No. It's not a good thing,"McLellansaid.

Pillayhad questions about the building where the trailer was originally housed. Court has previously heard that the trailerwas first brought to Metro Trucking on Seaman Street, which police had deemed a "secure facility."

But Metro Trucking was not an appropriate place to conduct a delicate forensics examination,McLellantold the court.There were mechanics working around the trailer in the garage at the time, she said.

"The only thing separating this particular crime scene a murder that you were investigating was yellow tape, correct?"Pillayasked.

"Yes,"McLellanresponded.

At the outset, those workers were also taking out their cellphones and taking pictures of what was going on.

"This is not a location where you want to engage in a detailed forensic examination?"Pillayasked.

McLellanresponded yes.
