I think they probably did confirm they walked home at the time - it's just so long ago, there's really not a lot out there online from back then.
Anyway, I was just mulling this over when I had a brainwave - I bet the case was featured on Crimewatch back in the day. And so I found it obvs
It's from 2000 and there was a full reconstruction done. It confirms the girls sacrificed their taxi money for chips, as
@Treesy19 suggested, and did walk home so it was out there.
The quality isn't great but it's here if you want to watch it - from 9.49 onwards.
They are appealing about a blue van on the reconstruction. I wonder if that was ever cleared from the enquiry? The police were asking about a van and driver that were seen in the CCTV released a couple of years ago but that one looks white.
