The next interviews were conducted by the Secret Service and occurred in the first week of December. They are included in WC Document 87.

In this interview less than two weeks after the assassination Williams recalls the elevator race as they broke for lunch and Oswald calling for the lift. On the 6th floor he sat at windows "in the centre of the building". A Dr Pepper bottle and chicken bones were left together on the floor. He didn't see or hear anyone and only ate his lunch for a few minutes. The lunch was "finished", not partially eaten, and he left immediately for the 5th floor before 12.15pm. (Note 12.15 is mentioned specifically!). Heard only two shots coming from 6th floor but did not hear shells and bolt action.
They went to west side windows and discussed what they should do as the shots had come from the 6th floor.
A policeman was seen near the stairway but Williams did not know if he was going up or down (note no mention of arrival by the elevator now). After five minutes they took the stairs down.
This interview essentially provided a similar story he told the FBI the day after the assassination except for some minor variance and added details. He now described the lunch consisting of a chicken bone sandwich and a Dr Pepper. He has been given the free pass by Day on the 25th November after Williams initial FBI interview. Day may have (inadvertently) provided a description of the final position of the chicken and bottle as found around 2pm on November 22 during that discussion.
Significantly he is sure he left before 12.15pm. No doubt there has been much talk between the TSBD workers of the events of November 22 and Oswald in the days since it occurred. Apparently he abandoned the idea of moving the lunchbreak earlier by 20 minutes. By this time the others members of the floor laying crew have been interviewed and they generally agreed the elevator race occurred at about 11.50am.
