They descended the stairs after Oswald. Thats how Vicky Adams saw Bill Shelley when she came down. Bill Shelley proved Adams needed to go buy a new watch.
Shelley proved no such thing;
Mr. BALL - Did you see Vickie Adams after you came into the building and did you see her on the first floor?
Mr. SHELLEY - I sure don't remember.
Mr. BALL - You don't.
Mr. SHELLEY - No.and neither did Billy Lovelady, who remarkably without being asked about Victoria Adams volunteered the following;
Mr. BALL - Who did you see in the first floor?
Mr. LOVELADY - I saw a girl but I wouldn't swear to it it's Vickie.
Mr. BALL - Who is Vickie?
Mr. LOVELADY - The girl that works for Scott, Foresman.
Mr. BALL - What is her full name?
Mr. LOVELADY - I wouldn't know.
Mr. BALL - Vickie Adams?
Mr. LOVELADY - I believe so.
Mr. BALL - Would you say it was Vickie you saw?
Mr. LOVELADY - I couldn't swear. Not only did Shelley and Lovelady not confirm the alleged encounter with Victoria Adams, but, according to the Stroud letter, her supervisor Dorothy Garner told Barefoot Sanders that the girls went down before Truly and the policeman (Baker) came up.
Obviously, Baker and Truly had already seen Oswald on the second floor before they came up to the 4th floor.
