Alastair Dempsey

Alastair Dempsey was a patient of Broadmoor who was turned into a vampire.

History
Alastair had once been working as a primary school teacher, and for the St. John Ambulance as a volunteer.

18 years before he became a vampire, his eight-year-old niece, Beth, lived for a short period in his house which he had inhabited for around twenty years at that time, as Beth's parents ‒ Alastair's sister, Sharon, and her husband, Nick ‒ were on holidays in Fuerteventura.

After Sharon and Nick came back from their holiday and picked their daughter up from Alastair, Beth told them that she had heard a "Ghost Lady" crying in the walls of Alastair's house.

A little while later, Sharon payed a visit to Alastair, only to find his house empty. When 24 hours had passed and he still hadn't shown up, Sharon called the police. They then searched the house and found a secret cellar. From the secret cellar's ceiling hung the corpse of a woman who was later identified as Anna Bailey, a whore Alastair had once ordered.

Around six hours after the police found Alastair's secret cellar, he was already the most wanted man in the country.

Alastair Dempsey was caught five days later by the police when he tried taking a ferry from Dover to France. It was eventually determined that he was a prolific serial killer who had murdered 36 women. He was sentenced a lifelong custody in a mental facility ‒ the Broadmoor Hospital.

Breakout of Broadmoor Patients
Along with many other Broadmoor patients, Alastair was turned into a vampire using plasma extracted from the fangs of Dracula himself. The resulting vampires were extraordinarily powerful for their age and easily broke out of Broadmoor, killing a number of people in nearby towns. Alastair was among the vampires who escaped the hospital and promptly set out to find more victims.
