What happened to Jackie Laverty?
In series one of Line of Duty, Jackie Laverty (Gina McKee) was an enigmatic businesswomen, who was having an affair with DCI Tony Gates (Lennie James).
Their relationship was one of the main reasons why DCI Gates was in trouble with AC-12, after he helped Laverty cover up a hit and run in which she killed her accountant, Gurjit Patel.
It would then be revealed that the hit and run was less accidental than it first seemed, after Laverty’s accountant clocked on to the fact that his client was running a money laundering operation with some dodgy people.
Laverty was eventually killed during a quiet night in with DCI Gates, when masked gang members burst in and slit her throat.
DCI Gates was hit over the head, and his fingerprints were placed on the murder weapon as a means of blackmailing him.
Later on in the series, Gates would be shown Laverty’s body in a warehouse freezer by the criminals, where he would attempt to come back and retrieve it.
However, the body was moved to Terry Boyle’s flat, where members of the OCG arrived to place it in the freezer.
Jacker Laverty was not referenced for several seasons, except for a minor detail in season two when her name is still in the missing person’s database.
Her body next appears in season five, episode four, when OCG members Ryan Pilkington, Miroslav, and Lisa McQueen visit Terry’s flat. When the freezer is opened it is revealed that Jackie’s body is still stored in the same freezer all these years later.
Jackie’s thawed body parts are then disposed of in McDade & Company Breakers Yard alongside the corpse of undercover cop John Crobett (Stephen Graham).
How did Jackie Laverty appear in season six?
In episode one, season six, Terry Boyle is interviewed by Joanne Davidson after his flat was raided during the Vella investigation.
Forensics found a clean flat, but they suspected it was too clean, and that the freezer was missing.
In episode three of series six Terry Boyle’s missing freezer turns up in a scrapyard - and forensic results reveal a blood deposit which is a 99.9 per cent match for Laverty.
AC-12 then realised her body could have been stored in the freezer by the OCG for years.
Who is Terry Boyle?
Boyle made his first appearance in the fourth episode of the first series, when he was played by original actor Elliott Rosen.
The character was seen to be bullied and manipulated by the OCG members Ryan Pilkington and Carly Kirk, who paid a visit to his flat and noticed that he had a freezer big enough for a body.
Boyle later attempted to report the matter to the police, but he wasn’t able to articulate what had happened.
The character then returned in series five – this time played by Tommy Jessop – when it was revealed that his flat was opposite the OCG’s HQ.
Ryan Pilkington visits him once again to quiz him over whether he had informed the police after they had raided the print shop.
During the confrontation, Ryan is seen looking for a beer in Terry’s kitchen, where he notices Jackie’s body in the freezer, suggesting that it had been stored there the whole time.
