Reports vary as to when she went out / was last seen. However, the independent witnesses seem to agree more or less.
The lady at the shop said that she saw her at around 20:20 / 20:30
A testemunha NN, proprietária da "Pastelaria ...", declarou que no dia 12 de Setembro a CC apareceu na pastelaria, pelas 8h 20m / 8 h 30m, a comprar um pacote de leite e duas latas de atum.
and the lady at the window saw her walking home at around 20:30 / 20:40.
Witness AA3, at around 8.30/8.40 p.m., saw CC [Joana Cipriano] walking up the stairs near the market, into the direction of her home, with a bag, a sign that she was returning from shopping (and we know that she did the shopping, from the deposition of witness NN). This witness, who was smoking at the window, stayed at the window for some time and verified that there was no movement on location, nor did she see any cars, or heard any screams. This means that, according to the rules of experience, and given the fact that the route is short, what is normal is that the minor returned home.
