Crown attorneys have outlined a series of links they say connect British Columbia teenager Amanda Todd and the Dutch man accused of harassing and extorting her in British Columbia Supreme Court Thursday.
They included a phone number, a passport photo and a video file named “AmandaTodd.wmv” that a Dutch police expert said was played on a device seized from Aydin Coban’s home in 2014.
Heather Guinn took the jury through Facebook records and testimony from a digital expert heard earlier in the trial, which she said showed links between numerous online aliases used to harass Todd, in some cases using the same device.
Coban has pleaded not guilty to extortion, stalking, communication with a juvenile to commit a sexual offense and possession of child pornography.
Guinn said one of the Facebook accounts used to harass Todd, which was linked to several others, was registered with a cellphone number.
It was the same phone number two women had previously said they received in May 2011 while communicating with a man about renting an apartment in Rotterdam.
Both women testified they met the man at the apartment and were later given a passport photo of him, he said.
Police found a copy of the same photo while searching Coban’s home, he said.
Guinn showed the photos on courtroom screens, which appeared to show Coban.
Another Crown attorney, Marcel Daigle, told the jury the video file “AmandaTodd.wmv.”
He cited earlier expert testimony from a digital investigator for the Dutch national police who said the video had been played one day in late December 2010 on a device seized from Coban’s home.
The date corresponded to a time when Todd was being actively harassed and extorted online, he said, just under two years before her death at age 15.
The Crown does not know what the video depicted because it had been deleted when Coban was arrested, Daigle said. But the Dutch expert said it had not been played online, but rather from a file that existed on the device.
Several devices found in Coban’s home had software described as an “anti-forensics” program used to erase files so they cannot be restored, Daigle said.
The jury has seen evidence throughout the eight-week trial showing that Todd’s stalker repeatedly demanded that he perform sexual “shows” on a webcam, or that sexualized images of the teenager be sent to his family and classmates.
The bully followed up on that threat, sending links to a pornographic website featuring Todd to his family and classmates, the trial heard.
At the start of the trial, Crown prosecutor Louise Kenworthy told the jury that Todd had been the victim of a persistent online “sextortion” campaign for three years before his death in October 2012, from of November 2009.
The Crown also focused Thursday on proving that 22 different accounts used to harass Todd on various online platforms were run by the same person.
Daigle highlighted the similarities in language and phrasing, along with references to previous threats sent by different aliases, saying there was an “overwhelming” cohesion.
The Crown is set to further expand its alleged ties to Coban on Friday.
Daigle showed the jury evidence that a photo of Todd exposing her breasts was used as a Facebook profile picture by one of the accounts used to harass her.
He recalled testimony from a Vancouver police digital forensics expert who said the only way to show a profile picture on Facebook was to upload the picture, meaning it had to have been stored on a digital device.
“If you accept my contention that there was a sextortionist, then this is evidence, this photo, this is sufficient evidence to conclude that the sextortionist had child pornography in his possession,” Daigle told the jury.
More than one of the accounts used to harass Todd displayed images of the teenager as their profile picture, he said, and evidence showed the images were created by capturing screenshots of a video that showed her exposing her breasts
Daigle told the jury it didn’t matter who originally created the videos and images depicting Todd sexually. What mattered, he said, was that the stalker owned and distributed the content, knowing it was child pornography.
Earlier this week, the jury heard a Facebook post from Todd in which he expressed fears that the person who harassed him would continue for the rest of his life.
Todd urged people to block one of the stalker’s accounts, saying a “sick pedophile” was blackmailing him, Crown attorney Kristen LeNoble said Wednesday.
