A female nurse in Scotland posed as a male doctor to female patients so she could induce them to send her explicit photos of themselves.

Adele Rennie, 27, a former staff nurse at Crosshouse Hospital in Ayrshire, posed as doctors named David Crolla and David Graham while using a voice-changing app as she perused social media sites to find victims.

Rennie contacted a 22-year-old woman on Facebook, identifying herself as Crolla; two years later she contacted the woman again saying she was Graham and that “his” mother was dying of cancer. According to prosecutor Scott Toal, when the victim heard Rennie the second time, she “noticed she had a strange voice,” and messaged, “Is this you? Surely not.”

The Daily Record reported that when Rennie contacted another victim, she said she was Graham and worked in intensive care at Glasgow Southern General Hospital.

A third woman, who worked in Glasgow with another victim of Rennie’s, received a love letter from Rennie. Toal said the woman, after finding out from her co-worker who Rennie really was, “felt sick and disgusted given the sexual conversation that had passed between them.”

In 2013, Rennie met a 23-year-old woman; she later contacted her on Facebook posing as Graham, then convinced her to send pictures of herself in her underwear. Rennie then sent the woman explicit photos of a man.

Rennie’s actions were discovered when her mobile phone called a victim by accident and the number matched Rennie’s Snapchat profile. When officers arrived at Rennie’s home, she had deleted her social media apps and internet history, and locked her mobile phone by inputting the wrong passcode.

Yahoo News reports, “She has now admitted 18 separate charges of stalking causing fear and alarm, sexual offences, data protection breaches, attempting to pervert justice and breaching bail conditions between 2012 and 2016.”

Sheriff Elizabeth McFarlane told Rennie, “I have just heard the most astounding narrative of facts I think I’ve heard in my entire judicial career.”
