Her brutal end launches a hunt which will grip Weatherfield.
In the build-up to the death, viewers of the ITV soap have had the chance to watch four alternative showdowns between Tina and potential killers — Peter Barlow, Carla Barlow, Rob Donovan, and Tracy Barlow — which are available on the Coronation Street website, itv.com/coronationstreet.
ITV said that there will be a “shocking twist” tomorrow night after her death plunge, just as the police begin their efforts to track down who is responsible.
In the coming months, the audience will see the killer desperately trying to cover their trail and evade justice.
Bookies William Hill stopped taking bets on the ITV soap whodunnit on Sunday at 9.46am after a “monster gamble” on rogue Tony Stewart from punters cut his odds from 100/1 to 2/1.
William Hill spokesman Rupert Adams said: “There was a real rush to back Tony — including a number of new account openings.
“We fully expect Tony to be unveiled as having done the dastardly deed.”
The odds on the killer are 4/6 for Rob Donovan, 2/1 for Tony Stewart, 5/1 for Peter Barlow, 10/1 for Carla Barlow and 16/1 for Tracey Barlow.
Michelle Connor and Simon Barlow were at 25/1 to be named as the culprit while builder Owen Armstrong, Steve McDonald, and David Platt were all at 33/1.
Odds of 50/1 have been available for Tyrone Dobbs, Dennis Tanner, corner shop owner Dev Alahan, builders Gary Windass and Jason Grimshaw, Kylie Platt, Lloyd Mullaney, Nick Tilsley, Tim Metcalfe, and Todd Grimshaw.
