Re screams, there are two separate reports from people in bed that I found had merged in my own mind - separated out below in case useful for anyone else (with apologies for repetition if not!)
Witness 1 @ 12.15
Home location not specified
“I woke at about quarter past 12 and there was a scream. It sounded like a woman’s scream towards the back of the park, where the river bank and pond is. Then 30 seconds later there was another scream. She must have screamed seven or eight times. All of the screams had gaps between them. The screams must have gone on for about 15 minutes. They sounded eerie, they sounded dark. Then I saw a male running."
Girl heard screaming in park just minutes after Libby Squire vanished
Witness 2 @ 12.30
Mother-of-two, Hull University graduate, dad is a retired policeman
Lives Heathcote St near junction with Wellesley Ave.
“We did hear screaming at 12.30 on Thursday night. I was just in bed reading. We do get a lot of students who live in the road that Libby lives in who use this road as a cut through. They go past screaming, shouting and singing. It’s not unusual. But this made us sit up. It sounded like someone being attacked. The scream sounded like it was coming from someone who was scared. It was someone walking quite close past our house. It was just one female scream. Then we heard other voices muttering very low, murmuring and then more screams and more male voices. Then we heard the slamming of a door. It sounded like a wooden door or a garden gate. It was just very odd. We didn’t think about it again until the police came round knocking on everybody’s doors on Saturday. We talked about it and remembered the scream and rang 101. It was really shrill and urgent. It made me sit up and think ‘Oh my God’."
