I am dutch as well. Its very hard to understand what she is saying. Especially from 0,35 when her voice volume drops. She starts mumbling and her fidgeting and selfsoothing stops. Its when she she says that she saw the bike. When the interviewer asks that's a logical question, how did the bike get there she says "i don't know how that came to be there". She obviously uses distancing language, not saying the bike but just "that". She does not know what to say and how. She stutters around 1:01. She has a constant sadness in her face. She start telling that her friend had the same bike and that's when she pauses a lot between talking. Half way through her story she stops explaining and start saying that she was busy with herself. When the interviewer asks how did the bike get there at 1:19 she starts stuttering extremely which she has not done yet. At 1:27 she shows a lot of fear microexpressions. At 1:37 she starts talking really fast when she explains why her friend was there.
I don't have the time at the moment to complete my analysis, however judging from the amount of redflags the chance that she is lying is great.
