Did Summer Spellman (Harriet Bibby) kill Theo Silverton (James Cartwright) in Coronation Street?

As it stands, a mountain of evidence is stacked against her – and George Shuttleworth (Tony Maudsley) is convinced that she was responsible for his death.
Last month, following wedding celebrations on the cobbles, Betsy Swain (Sydney Martin) found his body in the corner shop backyard. Attentions initially turned to George, who was noticeably absent for much of the evening, and then to his partner Christina Boyd (Amy Robbins).
DC Kit Green’s (Jacob Roberts) theory is that Gary Windass (Mikey North) is responsible, though his alibi has been backed up by wife Maria Connor (Samia Longchambon).
Earlier this week, George was startled to find a very incriminating page of Summer’s journal, that detailed her desire to aim a gun at Theo’s head. Summer was already looking visibly unnerved whenever the murder investigation was mentioned, and had even decided to move to America to escape the madness.
She was furious to find George and Christina rifling through her diary, and proceeded to burn the evidence in the back yard.

George noted that this could’ve been seen as evidence, and that it intensified what could be perceived as a guilty demeanour.
Little did they realise, over at the police station, attentions were already beginning to turn towards her. While flicking through her wedding photos with Kit, Lisa Connor-Swain (Vicky Myers) clocked a photo of Summer chatting to two of the partygoers – wearing the brooch that had been found on the floor of Theo’s flat.
In today’s episode, Summer was whisked into the station and interviewed under caution.
She presented the photo of her wearing the brooch, and questioned how it would make its way across the road and upstairs into the scene of the crime.
Summer denied all knowledge, saying that it must’ve fallen off her while she was leaving the wedding party and that Theo had picked it up. Connor-Swain looked unconvinced by her reasoning, but allowed her to leave.
Upon returning to the cobbles, Todd Grimshaw (Gareth Pierce) tore strips off the copper for bringing Summer in, insisting that she had nothing to do with it. He also suspected that George had reported her, though this wasn’t the case.

He whole-heartedly apologised for going through her belongings, but when she explained about the brooch, his suspicions were aroused once again.
George asked Summer whether she went to the flat that night, though she lied through her teeth and said that she hadn’t. A telling flashback took us back to the fateful evening, as George spotted Summer rushing off from the direction of the corner shop.
Why is Summer lying, and did she kill Theo?
