Both Earline Roberts and Gladys Johnson, the wife of the co-owner of the house (apparently she either owned it or the property it was on (it's not clear) before she married), testified that they never saw Oswald go out at night. Johnson said that she spent most of her evenings in the "back" of the house and wouldn't know about all of the goings of the tenants. Roberts said she never saw Oswald leave at night.
From Johnson's testimony:
Mr. BALL. Did he go out nights, any?
Mrs. JOHNSON. I just really never did see that man leave that room.
Mr. BALL. After he came back from work?
Mrs. JOHNSON. Yes; he stayed very closely but he did tell me he would be leaving to go home over weekends--no; he didn't say "home," he said I will leave to go to Irving over weekends and won't return until Monday."
From Robert's testimony:
Mr. BALL. Did he go out any at night?
Mrs. ROBERTS. No.
Mr. BALL. Did he stay home every night?
Mrs. ROBERTS. Yes---he stayed home every night---I didn't ever know of him going out. If he did, he left after I went to bed and I never knew.
If Oswald did go out to use the pay phone across the street - and according to Marina he regularly called her after work - it seems that Roberts would have seen him leave for at least some of these calls. So the "He used a pay phone across the street" claim seems suspect.
