Former IRA hunger striker Tom McFeely refused to apologise to displaced Priory Hall resident Stephanie Meehan, whose partner Fiachra took his own life.
Ms Meehan is credited with prompting the Government's latest response to the crisis by writing a heart-rending letter to Taoiseach Enda Kenny.
She has claimed the stress caused by being forced to move out of their apartment "pushed" Fiachra to take his own life in July.
Asked by a Sunday paper if he would say sorry to Ms Meehan McFeely replied: "For what? Tom McFeely did not build Priory Hall. Tom McFeely's company did. Tom McFeely didn't."
The €200,000 cash pile discovered in the disgraced property developer's former home looks set to be kept by the State after he denied all knowledge of the money.
A garda source told the Herald last night the massive sum was "almost certain" to remain in the Government's coffers after McFeely said it was not his.
"Unless a legitimate owner is identified, it won't be going anywhere," the source said.
NAMA, the State-owned body that repossessed the Ailesbury Road property last year, is watching developments.
McFeely has also claimed that money found under a bathtub didn't belong to him.
The Herald first revealed that €140,000 was discovered by a plumber under a bathtub in Ailesbury Road last month. In a subsequent search by the Criminal Assets Bureau, a further €60,000 was found.
The house, which is named Coolbawn, was sold by NAMA for €2.6m in May.
Gardai are confident that the money was placed there in recent years and well after McFeely bought the property in 2001.
The news of the find has shocked the displaced residents of Priory Hall, who say it should be used to resolve the problems at the troubled Donaghmede complex.
McFeely is due to appear before Dublin District Court tomorrow.
The court previously heard that he had failed to cover a €24,288 bill for services obtained from MCR Personnel Ltd. He could face a three-month jail term.
