Tapp suspect dies without charge
A KEY suspect in the unsolved murders of Margaret Tapp and her nine-year-old daughter Seana has died without being charged.
Homicide squad detectives never eliminated Kaye Bradtke-Stevenson from their list of several persons of interest in the 1984 case.
She found evidence which confirmed her doctor husband, John Bradtke, was having a long-running affair with Ms Tapp, including finding a sex tape of him and Ms Tapp.
Ms Bradtke-Stevenson — who died recently aged 75 — was a person of interest because police thought she might have arranged for a paedophile friend of hers to kill Ms Tapp, 35, and her daughter.
The paedophile is also still on the homicide squad’s list of persons of interest who may have murdered Ms Tapp and raped and murdered Seana.
Police secretly tapped the telephones of Ms BradtkeStevenson and the paedophile, but didn’t get enough evidence to charge them.
The police affidavit in support of the bugging application said detectives had information Ms Bradtke-Stevenson had threatened to kill Ms Tapp and Ms Bradtke-Stevenson had attempted suicide in the hope of persuading her husband to stay with her.
The paedophile’s wife told police she believed her estranged husband was responsible for the murders and that Ms Bradtke-Stevenson gave him about $50,000 a few months before their deaths.
She said in a sworn statement her husband had once mentioned the Tapp murders to her and he said they had been killed because Ms Tapp “was evil” and had “an adulterous relationship with Dr John Bradtke” and “deserved to die” for the hell she put Ms Bradtke-Stevenson through.
Police have an affidavit sworn by Ms Bradtke-Stevenson on April 11, 1995, in which she described a loan of $52,000 to the paedophile in early 1984.
Margaret and Seana Tapp were killed in their Kelvin Dr, Ferntree Gully, home in 1984. Dr Bradtke bought the home for Ms Tapp and it was their love nest during their affair, which ended with Dr Bradtke’s death in a 1983 car accident.
Cold case investigations are never closed and any new information received will be thoroughly investigated.
