This young woman’s overdose not only ended her life but gave other victims the courage to come forward and speak to police about years of grooming, heroin addiction, and forced prostitution orchestrated by older men preying on vulnerable women.
The new BBC documentary, ‘Caitlin Hanna: Trafficked in Belfast’, airing on BBC1, powerfully exposes the devastating cycle of exploitation, control, and addiction that ensnared Caitlin and others, shining a light on the dark underbelly of sexual exploitation in Northern Ireland.
Caitlin’s Downward Spiral and Exploitation by Derek Brown

Caitlin Hanna, once a bright and academically gifted teenager, began a heartbreaking decline in her teens marked by addiction and vulnerability.
Her mother, Deborah Hanna, recalls the painful physical deterioration she witnessed, including hair falling out and arms hidden under long coats to conceal track marks. Deborah describes one unforgettable night seeing her daughter in such a ravaged state: “Her hair was falling out. It was just horrendous. It was like watching her dying in front of your eyes and not being able to do anything about it.” Despite numerous police visits and attempts to intervene, Caitlin moved between family, aunts, and assisted living facilities, increasingly entangled in a dangerous lifestyle.
Derek Brown (62), who began exploiting Caitlin when she was just 16, groomed her with false care—providing shelter, food, and heroin supplies to gain control. Survivor Rebecca Whyte explains Brown’s tactic: “He acted soft, he acted caring…
If you were taking heroin Derek didn’t just give you money for heroin, he would have supplied it as well. There was an aspect of safety around him but that was his approach in getting you under his control.” Brown was later sentenced to six years in March 2025 for human trafficking, controlling prostitution for gain, sexual assault, paying for sexual services, and supplying Class A drugs, with half the term in prison.
The Network of Exploiters and Convictions

Brown operated within a network of elderly men targeting addicted and homeless young women. Raids uncovered videos at Martin Heaney’s home showing exploitation, linking to Brown’s activities. Other convicted individuals include:
- Oliver MacCormack (72), serving nine years (increased on appeal) for 40 convictions including human trafficking, drug supply, and controlling prostitution.
- Kenneth Harvey (74), jailed for two years in 2024 for human trafficking and paying for sexual services.
- Robert Rodgers (79), given a two-year probation order in 2024 for brothel keeping and controlling prostitution for gain, using his Antrim Road flat as a brothel.
Family Grief, Survivor Courage, and Disturbing Buyer Preferences
Deborah Hanna met Brown weeks before Caitlin’s death and recalls the horror of seeing an older man with her daughter: “If I had known exactly what was going on he would never have drove out of that garage with my child in that car.” Caitlin expressed desires to change, telling police in interviews, “I do try my hardest. But I always fail in the end.” Her post-mortem revealed death from methadone, bromazolam, and pregabalin overdose—drugs found with Brown, who deflected blame during arrest.
Survivors like Rebecca Whyte came forward to prevent future victims: “If I don’t actually speak up then there is going to be a girl after me. There could be a child after me.” Research from the Sexual Exploitation Research and Policy Institute (SERP) reveals a chilling reality: buyers prefer women appearing most ravaged by addiction, associating it with power and control rather than mere sex. SERP director Ruth Breslin notes survivors report healthier looks meant fewer clients, highlighting the perverse dynamics at play.
This case underscores the hidden dangers of sex trafficking in Belfast, where vulnerable women are groomed from teenage years into cycles of addiction and exploitation. The documentary includes chilling body-cam footage and interviews, serving as a call for awareness and action against such networks. Caitlin’s story, though tragic, empowered others to break silence and seek justice.
