business. The day she died one of the neighbours recalled how Emily was supposed to be picking her ten-year-old son up from school. ‘When I got back my husband was waiting for me at the bus stop,’ said the neighbour, who lived just along the road from the Jackson family. ‘I thought something was wrong. And when we got home the boy was sat with a policeman in their house … they [Sydney and Emily] often used to go out but we thought they were going to the bingo in Leeds, we never realized what she was doing.’

      After the death of their son, which Sydney said Emily never recovered from, they began to live from day to day. ‘We decided life was too short, we would live for today and not bother about the future. Sometimes she would go out alone, and I would meet up with her for a drink later on. But I do know that she never went in pubs on her own. She’s been in the Gaiety five times at the most, and always with me. We got on together as well as most. We both believed in having a good time – after all, why stop in every night? We believed in having fun while we could.’

      Sydney remained strong and reasonably composed for the sake of his children after the murder, but went through a difficult time as he realized he was under suspicion for killing his wife. The day after Emily’s body was found the door-stepping journalists were rewarded when Sydney opened his heart to them. Sitting in the lounge of his semi-detached house, holding his head in his hands as he wept, he told them: ‘I know what people are saying – but I didn’t do it. There’s nothing I want to say to the man who did it, there’s nothing I can say, but if he’s done it once, he’ll do it again. I just pray they catch him.’

      The information about Emily’s secret life was clearly an awkward embarrassment. Emily’s married sister refused to believe the things being said about her: ‘It’s time someone denied what is being said about Emily going into clubs and so on. She just wasn’t that kind of person.’ Unfortunately for Emily’s relatives, the press had quickly been let in on the details of her secret life. Hoban had no choice but to admit she had been soliciting about the time she was killed. Moreover, he could not ignore the obvious link with the McCann murder. He believed he had a duty to warn women who earned money by selling sex that they were in mortal danger. ‘While this man is at large no prostitute is safe,’ he declared.

      Sydney Jackson made frequent visits to the police station to answer questions, insisting he had not killed his wife in revenge for her becoming a prostitute. Eventually Dennis Hoban went to reassure him that they knew he was innocent. He pledged that his detectives would find the man who killed his wife.

      The police had taken away the Commer van containing Sydney’s tools and equipment for his business, so he couldn’t work or earn money. The vehicle had stood, with the ladder on the roof rack, at the Gaiety car park when Emily was murdered. For a while police thought it might have been moved. They were told Emily went touting for business in the van, sometimes taking customers in the back for sex. One look in the rear of the vehicle told them this was an unlikely passion-wagon the night she died. The materials for the roofing business filled up the inside. It was filthy and reeked of bitumen. There was a huge vat for heating tar, gas bottles, cans of paraffin, rolls of roofing felt, half-empty bags of cement, buckets containing trowels and other paraphernalia. Forensic experts gave it a thorough inspection. It was a well-used and abused vehicle, with the front bumper almost hanging off and several dents in the rear nearside panels. Four fingerprints were found that could not be eliminated. They also never determined who left a fingerprint on a lemonade bottle in the van, or another on a sweepstake ticket found in Emily’s handbag.

      Two days into the murder hunt Hoban appealed for women who worked the streets in the area to come forward. He announced that Emily used her van to solicit clients. ‘Sometimes she would leave the van in the Gaiety car park and go with clients in their own cars, when they would drive to some secluded place for sex. It was probably on one of these excursions that she met her killer.’ Newspapers quickly linked the murder of Jackson with that of McCann: ‘RIPPER HUNTED IN CALL-GIRL MURDERS’ announced the Sun on 23 January.

      A month later a witness came forward to say she had actually seen Emily around 7 p.m. getting into a Land-Rover. Police had begun questioning all convicted and known prostitutes in the area. One, a nineteen-year-old streetwalker, had been casually chatting to Emily moments before she got in the vehicle. A description of the driver, a man with a bushy beard, was widely circulated and an artists’ impression issued to the media. All Land-Rovers registered in West Yorkshire were checked, with negative results. Some time later a man answering this description, the owner of a Land-Rover registered in Essex, was interviewed and cleared. He had been temporarily staying in Leeds and admitted consorting with prostitutes. However, he denied that on the night in question he had been out looking to pay for sex with a woman. He had a cast-iron alibi. Some detectives believe he may well have picked up Jackson, and even had sex with her, but denied it emphatically because he had been driving while disqualified. There were searches for other vehicles. Sydney told police Emily had spoken of one of her clients as being ‘funny’ – they failed to locate him or the Moskovitch estate car he drove. Another witness saw a dark blue ‘L’ registered Transit van near the murder scene around 3.30 a.m. A list of 329 vehicles registered in Leeds was drawn up and 278 owners were eliminated from the investigation. The remaining fifty-one were never traced. It proved another frustrating investigation.

      No attempt was made to trace the boots the killer wore. Hoban thought too many workmen in the city used this type of footwear to waste time on this particular line of inquiry. It did suggest the killer was not an office worker, but was perhaps involved in manual work. He sent an urgent telex to police stations in West Yorkshire asking that anyone brought into custody wearing similar boots, who might have a vehicle containing tools, such as a workman’s van, be held for questioning. He also wanted local criminal intelligence cells in collators’ offices to begin examining records for the names of people convicted of series attacks on prostitutes.

      Hardware shops were visited to positively identify the kind of weapon used. Hoban was convinced a cross-head screwdriver was the answer; but Gee, when he carried out a variety of tests using different tools, could not reproduce the same kind of wound. When he tried to produce wounds with a Phillips screwdriver, he found that although the flanges of the tip would indeed produce a cruciform wound, as soon as you drove the weapon in with any degree of force, the rounded shaft destroyed the pattern and left simply a round hole. He began searching for a weapon with flanges all the way up its length. ‘The explanation of course had to be that some of the wounds were not driven home with sufficient force to extend right up the shaft of the weapon, but there were fifty-two of them and it was difficult to follow the tracks of all,’ he said later.

      Gee wrote confidentially seeking assistance and suggestions from a number of senior forensic pathologists around Britain and Ireland, including the eminent Professor Keith Simpson. All kinds of possibilities were offered: a carpenter’s awl; the implement in a boy scout’s knife for taking stones out of horses’s hooves; a spud lock key; a roofing hammer; and a reamer. Several pathologists backed the idea of a Phillips screwdriver. ‘I am surprised that you had difficulty in getting a Phillips screwdriver through the skin,’ replied Professor Keith Mant of Guy’s Hospital. ‘I have seen fatal stab wounds from such instruments as pokers, and in one case, a boy was stabbed through the heart with a poker during some horseplay with his brother, who had no idea that he had hurt the deceased, especially when he subsequently walked upstairs to his bedroom. He was found dead in bed the next morning – no blood having issued from the wound!’

      More media coverage was generated when a police Range Rover, complete with flashing blue light on top, toured the Chapeltown and Roundhay Road area. It contained a large photograph of Emily Jackson and appealed for witnesses who might have seen her on the night of the murder to come forward. Loudspeaker vans toured Leeds, interrupting weekend rugby and football matches. Cinemas and bingo halls suspended proceedings to broadcast appeals from the police. Publicity about two prostitutes having been murdered within three months caused some local women to stop soliciting. Others said they had no choice and accepted the risks: ‘There is always a danger when you do this game, but you have got to find a quiet spot, a dark spot,’ said one.

      Everything told Hoban that Emily Jackson had been picked up in a vehicle while offering herself for sex; she was taken less than half a mile from the Gaiety to
