SL and Mr Kipper were sighted outside 37 Shorrolds Rd, within a narrow time frame by several witnesses whose recollections, taken together, are strongly corroborative.
The alleged bundling of SL into a car by Mr Kipper outside 37 Shorrolds Rd as witnessed by HR, could be explained by the actions of an enthusiastic, over-attentive, paramour - Mr Kipper - keen to whisk SL away, possibly back to Stevenage Rd (where SL's Fiesta had been parked earlier) and/or Bishops Park for a glass of bubbly. No one can say. It's largely speculation from that point although, as we know, there were later, less secure sightings, putting her in the general area of Bishops Park/Stevenage Rd/Fulham Palace Rd.
It's interesting to note that Mike Barley of the investigation team is on record as believing SL drove directly to Stevenage Rd from Sturgis. By his account, presumably, she was picked up from there and taken to Shorrolds Rd, possibly for a genuine viewing or perhaps more likely, to flesh out her cover story for meeting up with Mr Kipper for other reasons. Jim Dickie, contrarily, states that he believes the reverse to be true and that she drove to Shorrolds Rd from her office. Either way, the police have SL firmly placed in Shorrolds Rd and I've yet to hear any credible hypothesis that she was abducted the moment she left Sturgis.
