Suffolk Strangler Steve Wright's father Conrad will appear on national TV this evening to reveal insights into the serial killer's early years, his theories about Wright's possible links to at least three other murders and his desperate hope that his son will one day tell him the truth.

Mr Wright, 81, a former RAF policeman, takes part in My Son the Serial Killer on Channel 5 tonight at 9pm. His son Steve is serving a whole life imprisonment for the murder of five women who worked in Ipswich's red light district in the final months of 2006.

Tonight's documentary sheds more light on Norfolk-born Wright's early years when he was abandoned by his mother as an eight-year-old and sees his father admit that his son appeared to live in a world of his own that he couldn't reach.

Tania Nicol, 19, Gemma Adams, 24, Anneli Alderton, 24, Annette Nicholls, 29 and Paula Clennell, 24 were killed by Wright within a 10-day spree which was described as 'the fastest selling killing spree in British history'.

Mr Wright said his son could have killed estate agent Suzy Lamplugh, who disappeared aged 25 in 1986, adding that he was 'troubled' by pictures in his son's collection of the two of them together – the pair had worked on the QE2 at the same time and Wright was on leave when Suzy disappeared.

And he recalled the period when Wright ran the Ferry Boat Inn in what was Norwich's red light district in the 1980s and when city sex workers went missing – Michelle Bettles, 22, was found strangled in Dereham after disappearing from Norwich in 2002 and had been a regular at the pub.

Two years earlier, sex worker Kellie Pratt went missing from Norwich and is presumed dead and in 1992, 16-year-old Natalie Pearman was strangled by a man she picked up from 'the block', her body dumped in woodland just outside Norwich.

Wright's father said he found the coincidences of the women's murders and disappearance at the time his son was living in Norwich 'troubling' and added: 'what happened to those girls – there are so many questions to my mind.'

Former Met detective Sue Hill said: 'I totally believe he is responsible for more deaths.'
