The identity of Karen's killer will soon be revealed in Fair City, and for the next seven days Detective Inspector Yates and Sergeant Deegan will shine the spotlight of suspicion on the key suspects in a bid to gather more clues for their investigation.
With DI Yates hot on the tails of Carrigstown residents and eager to pick holes in their stories, it seems that all of the suspects are starting to buckle under the pressure.
Earlier in the week Wayne was asked back to the Garda station and was once again questioned about the night of Karen's murder.
In a teaser video for the eagerly-awaited upcoming episodes, a nervous Wayne pleads his innocence, saying: "Me have an affair with her? Look, that was all in her head.
"She had problems. Okay, I mean mental problems. Anyway, Orla knew it didn't happen and that's all that matters to me.
"And if you're looking for somebody with a grudge against her - Oisín Brennan."
Find out what happens next on Fair City on RTÉ One at 8pm on Sunday night.
