Her uncle just answered questions thrown at him: did he own a cleaning business, has he ever owned one, has he ever employed her. He answered them truthfully, no he did not.
Her father said she had been planning the trip since the start of the year and he told her not to go to Colombia and she said she wouldn't. next thing he knows she in the news arrested for drug smuggling. He then said she had a habit of lying to people about what she does and where she goes.
I don't think either of them were trying to throw her under a bus and not support her, but they clearly are not going to lie for her and neither sold their story.
Her boyfriend sounds dodgy as well as her.
