Life sentence for prolific online predator who targeted children internationally
In a landmark sentencing at Belfast Crown Court on Friday, 26-year-old Alexander McCartney was given a life sentence for a series of crimes, including child sexual abuse, blackmail, catfishing, and the manslaughter of a 12-year-old American girl who tragically took her own life in 2018. The charges, which McCartney pleaded guilty to, involved a total of 185 offenses affecting at least 70 victims in multiple countries, according to the Northern Ireland Public Prosecution Service (PPS).
Catfishing and blackmail tactics revealed
McCartney’s methods involved “catfishing” — a practice of creating fake online identities to deceive others. Authorities reported that he posed as young girls on social media to gain the trust of minors, manipulating them into sending explicit images. Once he acquired these images, he would blackmail his victims into sending further content or performing increasingly dangerous acts, according to the PPS statement.
Acting head of the PPS Serious Crime Unit, Catherine Kierans, noted McCartney’s extensive efforts to exploit vulnerable individuals. “All McCartney’s victims were young, innocent people as young as 10 years old, struggling with identity and body image issues, and had reached out for help on social media,” Kierans said.
Victims’ lives altered, including tragic suicide
Among McCartney’s 70 confirmed victims was a 12-year-old girl from the United States who took her own life during an online interaction in which McCartney was threatening her, Kierans noted.
Although McCartney and the young victim never met in person, his influence over her was devastating. In total, McCartney targeted an estimated 3,500 minors across Northern Ireland, Ireland, Great Britain, the United States, and New Zealand, manipulating many into explicit exchanges.
McCartney used Snapchat to target victims
McCartney’s platform of choice was reportedly Snapchat, a social media app frequently used by teens. In response to the case, Snapchat issued a statement saying, “The sexual exploitation of any person is horrific and illegal, and our hearts go out to the victims in this case.” The platform assured that it works to prevent and report violations of this kind to the authorities and includes “extra protections for teens to make it difficult for them to be contacted by strangers.”
Continuing investigations to identify more victims
As McCartney serves his life sentence, with a minimum term of 20 years before parole eligibility, authorities continue efforts to identify additional victims. The PPS is actively working to bring justice to those affected by McCartney’s exploitation and to support victims in their recovery from the traumatic experience.
