Michelle's last FOUR scenes were murder*; CORRIE: BIGGEST SOAP MYSTERY SINCE J.R.
CORRIE chiefs are bidding to whip up a Dallas-style hysteria by filming FOUR different versions of Tina McIntyre's death.
More than 21million Brits tuned in when the person who shot scheming J.R. Ewing was unmasked in 1980.
And ITV bosses hope to ramp up the same kind of tension over how Tina - played by Michelle Keegan, 26 - dies in a balcony-fall after being ditched by her married lover.
Four characters are in the frame - and the culprit won't be named till May 27.
Suspect No1 is her lover Peter Barlow (Chris Gascoyne).
Suspect No2 is his pregnant wife Carla, played by Alison King, who said: "When Carla confronts Tina emotions will be running high because hell hath no fury like a woman scorned."
Suspect No3 is ex-con Rob Donovan (Marc Baylis), whose dodgy dealings were rumbled by Tina.
Suspect No4 is Tina's enemy Tracy Barlow (Kate Ford), who was convicted of murdering an unfaithful lover in 2006 but was later freed from jail after an expert witness was discredited.
Each of the four have been filmed having a showdown with Tina (see pictures, left) - and you can preview them from noon tomorrow at itv.com/coronationstreet.
Michelle is leaving the soap after six years to move to London with ex-Towie star Mark Wright, 27.
