Python deaths trial hears details of snake's attack on sleeping boys

The many injuries inflicted on two boyskilled by an African rock python were quietly laid out before the jury in a Campbellton, N.B., courtroom on Thursday.

Forensic pathologist Dr. Marek Godlewskiperformed the autopsies on Connor Barthe, 6, and Noah Barthe,4, three days after they were killed while on a sleepoverat their friend's house next door.

Their friend's father, Jean-Claude Savoie, is standing trial on two counts of criminal negligence causing death arising from the deaths of the Barthe boys on Aug. 5, 2013.

Speaking ina quiet voice, and witha Polish accent, Godlewskigave a medically and scientifically detailed account of his findings in each of the autopsies.

Godlewski described 13 groups of linear puncture wounds in groups of four that were found on Connor's body. Puncture woundsare wounds deeper than they are wide.

Many of those wounds were on Connor's face and neck.

The pathologist had requested to examine the python's head so he could compare its teeth to the puncture wounds.

"The pattern fits with the head," said Godlewski.

"I would say they are compatible with bite marks or bite attempts."

But those bites did not kill Connor

There were also "pattern abrasions" on the skin and hemorrhagesin the muscles of the neck.

Asked by the Crown prosecutor for the cause of Connor's death, Godlewski replied: "Underlying cause snake attack."

"Immediate cause, asphyxiation by neck strangulation."

The autopsy findings for four-year-old Noah were similar, with multiple puncture wounds and abrasions.

On several places on Noah's body, "flaky material" was found, said Godlewski.

"Scales," he said.

There was more blood both dried and liquid on Noah than on Connor.

Cause of death, he said, was"likelytraumatic asphyxia by constriction."

Vent cap on air duct off

The plastic vent cap on an air duct leading to the python enclosure in Savoie's apartment continued to be a focus of his trial.

Through that air duct, an African rock python is believed to have escaped its enclosure and killed the brothers in their sleep while staying withSavoie's son in Campbellton.

Evidence from veterinary pathologist Dr. James Goltzon Thursday put the snake's measurements at 12 feet, four inches (nearly3.8 metres)in length and weighing 53 pounds (just over 24 kilograms). The python's circumference at its largest was 12 inches (30 centimetres). Its diameter was4.25 inches (nearly 10.8 centimetres), said Goltz.

As the trial resumedin the Court of Queen's Bench, John O'Brien was called to the stand. O'Brien is the boyfriend of Mandy Trecartin, the 35-year-old mother of the dead boys, but is not their father.

O'Brien told much the same story as Trecartin relayed in her testimony on Wednesday a day of fun and adventure for the boysthat ended in the unthinkable.

O'Brien testified he was sleeping at Trecartin's apartment the morning Savoie came banging on the door, waking them up, and yelling, "Oh my God, the kids are dead."

O'Brien said he got out of bed and went to the building next door to see what was going on.

"I checked for a pulse. They were both blue," he said.

Vent capon the floor

O'Brien estimated he had been inSavoie'sapartment about 20 times in the previous months. When Crown prosecutor PierreRoussel asked if anything attracted his attention in the python enclosure, O'Brienresponded; "The cap. It was on the floorand not where it should be."

O'Brien said he saw the cap on the floor within a week of the boys being killed.

"I never thought anything of it."

He didn't notice the air duct the cap was supposed to cover as he didn't look at the ceiling of the python enclosure, he said.

O'Brien said he saw the vent cap on the floor on all 20 occasions he was in the apartment.

Contradictory testimony

However, on cross-examination,defence lawyer LeslieMatchimproduced transcripts ofO'Brien'stestimony at the preliminary hearing in November 2015 when O'Brien said he was inSavoie'sapartment 10 times, not 20 times as he had just testified.

O'Brien countered that perhaps it was 15 times.

Matchimalso pointed to preliminary hearing testimony in which O'Brien stated he saw the vent cap on the floor of the snake's enclosure "at least once."

"That's a far cry from 20," saidMatchim.

"Is there a difference if it was 20 times or once?" askedO'Brien.

Under questioning, O'Brien conceded his memory of things more than three years ago may be fading as time marches on.

"I can only guarantee I seenit once," said O'Brien.

The jury has been told that for a charge of criminal negligence causing death, the Crown must prove:

• Savoie had a legal duty to care and protect the Barthe brothers.
• That he failed to do so and showed wanton and reckless disregard for their lives in that failure.
• Savoie's actions showed a marked and substantial departure from the actions of a reasonable person.

Zoo co-ordinator testifies

Magnetic Hill Zoo co-ordinatorBernard Gallant was called as a Crown witness and testified to knowing Savoiesince the mid-1990s due to Savoie's interest in reptiles.

Over the years, Gallant came to refer reptile issues in northern New Brunswick to Savoie.

Gallant saw the African rock python previously when officials from the Canadian Wildlife Service brought it to the Magnetic Hill Zoo andasked them to take it. However, the zoo had no room and referred them to Savoie.

Gallant was also asked about what measures were taken when building enclosures for large snakes.

"Whenever we construct anything we err on the cautious side, build it tougher than we think we need," said Gallant.

The snake got into an air duct and its weight caused it to crash the ceiling tiles in the adjoining living room where the Bartheboys were sleeping.

The Crown prosecutor pointed Gallant to the living room ceiling tiles on exhibit the typical lightweight ceiling tiles used in finishing basements and asked if that type of material would be used by the zoo in a snake enclosure.

"No," replied Gallant.

Goltz, the provincial veterinarian who performed the necropsy on the python, took the witness box next.

"There was nothing much that was abnormal," said Goltz. "In the end I found nothing of note."

He also found nothing in the snake's digestive tract.

Goltz said that led him to believe the snake hadn't eaten in at least 24 hours.

The trial resumes Friday morning at 9:30 a.m. when the Crown said it will call its final witness, reptile behaviour expert Robert Johnston of Toronto.
