Who killed Karen? It's been the question plaguing all of Carrigstown for weeks, and now the culprit has finally been revealed.
Warning: Spoiler Alert!
At the end of March, Karen met her untimely end after Wayne found her injured and bleeding in his kitchen.
After many twists and turns, with the police investigating multiple suspects, the killer was finally revealed on Thursday night's episode of Fair City.
Sean, Orla, Wayne, Oisin and Carol were all in the line of suspicion, but in the latest instalment viewers were shocked when it was unveiled that in fact pregnant Kerri-Ann was responsible for the horrific crime.

Fair City viewers were delighted with the unexpected twist, saying they were "shocked", that they "didn't see it coming" and that actress Jenny Lee Dixon put in a "flawless performance".

An award-worthy performance by Jenny Dixon over the last few weeks. Soap is very rarely rewatchable, but the way she carries that secret is worth a second look. A lot of scenes are different in retrospect. #FairCity

Actor Dave O'Sullivan, who plays Kerri-Ann's husband Decco in the soap, tweeted after the episode that "the fallout in the coming weeks is just as explosive".

In a new clip from Sunday's upcoming instalment from the soap, the plot thickens as Kerri-Ann makes her plan to escape Carrigstown.
A tearful Kerri-Ann tells Decco: "I have to get out. I can't explain, if you don't trust me I understand, but I want to leave.
"I'm not the same. If you want to stay I can't force you, but I'm getting out of here."
