Jacqueline, 21, appeared on Good Morning Britain and admitted she thinks there are more murders to come.
She said: “I think it could be a serial killer.” Jacqueline also revealed she believes the killer will be someone new to the Square.
There have been a lot of new characters popping up lately, including Charlie Cotton, who may or may not be Dot’s grandson, and Aleks, the shady market inspector.
It was also revealed this week that Ben Mitchell was released from prison a month ago, which means that he could well be behind the murder.
Jacqueline added that she can’t stop trying to work out who the killer is, saying: “I honestly can’t stop, it’s driving me crazy! There are little hints in the script that I’m trying to pick up on but it keeps changing.”
We saw on last night’s episode how former flames Lauren and Peter, Lucy’s brother, leant on each other following the murder, and ended up kissing.
Jacqueline revealed that Lauren and Peter, who is played by Ben Hardy, could possibly be getting back together, and said: “It was kind of awkward because [Ben and I] have been friends for a year now!”
