Rob Green, the nephew of Hilda Murrell, will address the audience of a public meeting being held in Shrewsbury on the 30th anniversary of her death, via the internet.
The meeting will discuss how recent revelations about the mishandling of the Hillsborough tragedy and the flawed inquiry into the death of Stephen Lawrence may have parallels with the way the murder of Miss Murrell, a renowned rose grower, was investigated.
Commander Green held a key position in Naval Intelligence at the time of the controversial sinking of the Argentinian battleship The Belgrano.
He says his book "contains new evidence which should have acquitted Andrew George – who was found guilty of her murder in 2005, and makes the compelling case that Hilda was abducted by the authorities to find out what she knew about the Falklands War and technical problems with the Sizewell nuclear reactor".
Miss Murrell was found brutally murdered in a field near Shrewsbury in 1984, having just gained permission to testify against the nuclear industry at the Sizewell B public enquiry.
The meeting will be chaired by broadcaster Chris Eldon Lee who has been following the case of 30 years. He said: "Andrew George was a slight youth of 16 at the time of Hilda's death and could not drive.
"Those close to the case reckon he could not have perpetrated the complex abduction and murder of Miss Murrell alone. As with the Stephen Lawrence and Hillsborough cases, we're convinced evidence has been withheld.
"It will be interesting to see what information is, or is not, released under the 30 year rule."
Other speakers include Hilda's friends Daphne Philips and Trina Child, her adopted niece who interviewed a prison inmate in 1991 who knew details of the murder.
The meeting is free but booking is recommended on (01743) 232236.
