The Yukon Supreme Court heard Wednesday how RCMP Sgt. Jim Giczi single-handedly captured two individuals following a shooting involving Cpl. Kim MacKellar of the Haines Junction detachment.

The forensic identification specialist for the Yukon said when he was dispatched to Haines Junction from Whitehorse on the morning of Sept. 26, 2011, he knew the matter involved an RCMP officer. He was told the incident involved multiple scenes.

The sergeant testified he'd also been told RCMP officers were still searching for two people who might be armed.

With more than 22 years on the force, Giczi testified that in his 11 years as a forensic specialist, he hadn't made a single arrest until that morning.

Normally, Giczi told Justice Leigh Gower and the jury, he shows up to collect evidence from a crime scene, like a break and enter, long after the perpetrators have fled.

Giczi said he got into his unmarked Ford 350 forensic truck with a camper on the box and began driving to Haines Junction.

Just before the Pine Lake Campground, he saw a members of the RCMP's emergency response team and the dog handler at a highway pullout.

He pulled over and told Staff Sgt. Doug Harris he would be going on to the scene at Madley's General Store, Giczi testified.

Back on the highway, Giczi said he soon noticed two people coming out of the bush between the Pine Lake Campground and the Pine Lake subdivision.

He radioed in the information, pulled over and watched as the two individuals walked down the subdivision road toward his vehicle, like they were looking for a ride.

Giczi told the jury he removed his pistol from its holster, stepped out from behind the truck door and identified himself as a police officer.

He ordered them to the ground. They complied, he told the jury.

Shortly afterward, other officers arrived at the arrest scene.

Giczi testified he recognized the man as Chris Cornell. He didn't recognize the woman, but learned her name was Jessica Johnson.

Sometime later, Giczi was led by members of the emergency response team to a wooded site near the campground, where the police dog had located a .375 H & H rifle hidden under the moss, the sergeant testified.

Cornell, 31, and Johnson, 22, were charged with attempting to murder Cpl. MacKellar and Shane Oakley by shooting at them with a rifle during a high-speed chase along the Alaska Highway, headed toward Destruction Bay.

They were also charged with using violence and dousing custodian Frank Parent with bear spray while stealing a safe from Madley's General Store.

Only Cornell is on trial at this time. The proceeding began last week with the selection of nine women and five men to serve on the jury. It's scheduled to go for another week or two.

The jury has heard how the corporal and Oakley, a deputy conservation officer, ended up riding together in MacKellar's police truck sometime after 6:12 a.m. on Sept. 26, 2011.

Jurors have heard there was a call on the police radio of a break-in occurring at the general store.

Oakley testified that when they arrived at Madley's, there was a black SUV parked parallel to the front of the store, as well as the custodian's truck positioned nose-first.

MacKellar pulled up to the passenger side of the black SUV, Oakley told the jury.

As the officer stepped out, the SUV darted backward. It slammed into the railing on the store front, then sped forward between the marked RCMP truck and the custodians truck.

The high-speed chase began in the morning darkness of late September, Oakley told the jury.

He described a wild chase, with items flying out the rear passenger door of the black SUV they were pursuing.

An explosion of glass inside the cab of the police truck ended the chase.

Oakley said he instantly looked to MacKellar and saw blood on the officer's face as the corporal began to pull over. He was favouring his left shoulder.

After walking the bloodied and injured MacKellar around the truck to the passenger seat, Oakley jumped into the driver's seat, turned the truck around, and headed for Haines Junction, he told the jury.

The court has heard testimony of how two employees of the Talbot Arms Motel were travelling from Destruction Bay to Whitehorse that morning. They came across a black SUV off the Alaska Highway, sitting up against the tree line.

After finding no one when they stopped to check, the employees returned to their cube van parked on the highway.

A man carrying a rifle and a woman walked out of the bush some distance away, explaining they were out hunting and had experienced trouble with their truck, the jury hasheard. The couple hitched a ride to the Pine Lake Campground.

The forensic specialist testified Wednesday about how he created an aerial view of the area showing Haines Junction and the spot of the "shooting” where glass and blood were found on the highway 31.8 kilometres from Madley's store.

Giczi explained the mark on the photo showing where the suspect black SUV was found in the ditch 12 kilometres beyond the shooting site, toward Destruction Bay.

He told the jury of how he photographed MacKellar's yellow RCMP patrol jacket.

It was stained with the colour of blood and had a hole in the upper left hand side. It was the same as he described taking pictures of the officer's regular duty shirt – stained, with a hole near the left-hand shoulder.

The corporal's bullet-proof vest worn under the clothing was stained red, Giczi told the jury.

He described documenting a dashboard radar unit with a hole through it.

The radar was lying on the floor in the front passenger side of MacKellar's police truck, next to a blood-red stain below the seat where the injured corporal had stumbled to with Oakley's assistance.

The identification specialist spent most of Wednesday afternoon testifying about items seized during the investigation, where they were seized, and when they were seized.

He told of taking DNA swabs from the rifle located near the campground, and swabs from the hands of Cornell and Johnson to check for gunshot residue.

Swabs were taken from the handle on the safe lying in the parking lot of Madley's General Store, Giczi testified.

He told the jury the pattern of blood on the phone in Madley's office indicated it had fallen straight-down.
