Next week, the body of Underworld boss Frank (Andrew Lancel) will be found on the factory floor by Sally Webster (Sally Dynevor).
Speaking to Soaplife, the actress claims that her character, who was raped by ex-partner Frank, "has more motive and opportunity" to kill the evil businessman.
When asked whether she believed Carla to be capable of killing Frank, King replied: "Yes, very possibly - she has more motive and opportunity than the other suspects.
"Frank has completely destroyed her life. She's a desperate woman who could do something desperate."
Bosses have already unveiled a promotional picture lining up Carla's boyfriend Peter Barlow (Chris Gascoyne), her closest friend Michelle Connor (Kym Marsh) and Sally's ex-husband Kevin Webster (Michael Le Vell).

Before Frank is killed, viewers will see him con Carla out of her share in the factory - not content with being acquitted of raping her.
Frank Foster's last scenes will air next Monday at 7.30pm and 8.30pm on ITV1.
