"At 2.30 am
another of the party guests attempted to ring the sisters on their phones, but the calls went unanswered."
"Bibaa, who lived in Wembley, and Nicole, of Harrow,
were part of a group of 10 people who gathered from 7.40pm on Friday for the birthday picnic in the 254-acre park."
"They were reported missing to police
late on Saturday"
"But DNA from the killer’s blood found at the scene has not been matched to any profiles held on the national database."
"He said it was not yet known whether the women were initially attacked at the picnic site, or within the line of trees where their bodies were found a short distance away."
