Becky Swain’s death in Coronation Street

While we never met Becky Swain on screen, viewers certainly know a lot about her. Becky has been mentioned over a hundred times since Lisa was made a permanent character on the cobbles.

We know that Matty and Logan Radcliffe were involved in Becky Swain’s death. She died on duty and was hit by a car during a police chase. There were also files that explained that Becky was being investigated for corruption shortly before her death.

Lisa’s now uncertain as to how Becky Swain actually died. Carla suggested that Lisa visited Logan Radcliffe in prison to get more answers as to how and why Becky really died. But, Lisa shut down this idea.

She then went alone and got the name Tia Wardley. Meanwhile, Kit Green has been doing some investigating of his own and has warned Lisa that DI Costello might’ve been involved in Becky’s corruption.

Coronation Street fan theory predicts DI Costello killed Becky Swain

With there being corrupt cops all of the time in Soapland, one specific Coronation Street fan theory has suggested that DI Costello might’ve actually killed Becky Swain and has been covering it up from Lisa ever since.

This evening, DI Costello was seen on the phone while informing someone that Kit and Lisa were sniffing around into Becky’s case but he’d ‘deal with it.’ But, did he have anything to do with Becky’s death?

The theory on X read: “Costello is definitely part of this whole thing. ‘He’s been worried about me since Becky died.’ He [bleep] killed her.”

Another person replied: “I think so too. I think he is a big part of the reason the Radcliffes got away with so much.”

But, what really happened to Becky? And, will Lisa Swain ever get answers?
