This is what I hear on the tape as R/TN are being interviewed by NG as she tries to learn who was in the MH earlier that evening:
NG: ...I mean earlier that evening.
TN: ...there was a repairman there, um,
R: J.
TN: my mother
(Italicized - sounds to me spoken simultaneously.)
TN: (continues) was actually...over...that night.
NG tries to review (...I couldn't hear you.) who visited the MH that evening:
NG: ...there was a repairman there. The cousin was there
TN: Yes, Mam.
NG: (continues) who police have investigated. Who else?
TN: My mother came by that night.
R: _?_ cousin.
NG: For what reason?
(Italicized - sounds to me spoken simultaneously)
R: Cousin wasn't there.
TN: ...that was um sometime between 7 and 8 PM that night (Voice noticeably cracks during "that night").
From above:
R: _?_ cousin.
NG: For what reason?
(Italicized - sounds to me spoken simultaneously)
It is the word R says before "cousin" ("__cousin"), that I cannot decipher: either "my" or "the."
It appears to me that during the above interview, when NG refers to "cousin," she clearly means M's cousin, JO.
However, it also appears to me that during the above interview, R knows that NG means M's cousin, and that is the individual who R appears to want to correct NG and TN about.
