Austrian man threatened to gas family
An Austrian man who held his daughter captive for 24 years and fathered her seven children repeatedly warned his captives they would be gassed if they tried to overpower him, a spokesman for investigators says.
Separately, authorities said Josef Fritzl forced his captive daughter to write a letter last year indicating he may have been planning to release her from the windowless dungeon where she lived with three of their children.
Police Colonel Franz Polzer said Elisabeth Fritzl wrote to her family, who believed she had fled to a cult, that she wants to come home but "it's not possible yet".
DNA testing on the letter proved that 42-year-old Elisabeth had written the letter, but Polzer said she was forced by her father to do so.
"He may have had plans to end the captivity at some point," Polzer told The Associated Press. "It just shows how perfectly he planned everything."
Fritzl's elaborate crime came to the attention of authorities on April 19 when one of Elisabeth's daughters, 19-year-old Kerstin, was admitted to a hospital suffering from an illness linked to an unidentified infection.
Baffled doctors then appealed on TV for Kerstin's mother to come forward because they needed information from her about her daughter's medical history. Fritzl then accompanied Elisabeth to the hospital, and her story came to light.
"It shows that he must have had a spark of humanity," Polzer said.
Meanwhile, Federal Bureau of Investigations spokesman Helmut Greiner said investigators were checking to verify whether Fritzl had indeed set up a mechanism that could send gas into the dingy, windowless enclosure as he had claimed during initial police questioning.
Experts are also checking another Fritzl claim that the reinforced door leading to the enclosure had a timer that enabled it to open automatically or be easily opened from the inside if he was gone for an unusually long period of time, said Greiner.
A man claiming to be a former tenant of Fritzl's, meanwhile, said he heard occasional suspicious noises from the area of confinement during his 12 years of residency starting in 1995.
Alfred Dubanovsky told the AP that he occasionally heard "knocking, banging" and what sounded like objects being dropped while living in a ground floor apartment of the building owned by Josef Fritzl and above the basement dungeon.
He told the AP that he asked Fritzl whether the noise came from the basement gas heater and Fritzl said "yes".
On another occasion, Fritzl bragged: "This house is going to make history one day," Dubanovsky said.
Fritzl told all residents of the apartment house that the basement was off limits and that they weren't allowed to take photos in the area, he said, adding that Fritzl threatened to evict those who broke that verbal agreement.
Fritzl once asked him whether he wanted to change his ground-floor flat for a bigger one on the upper floor but he declined, Dubanovsky said.
Days before Elisabeth told police of her 24 years in captivity, law enforcement officials had become suspicious and started investigating Fritzl, according to a police statement.
It said police decided to compare DNA samples of the hospitalised Kerstin and of Fritzl, along with family members living with him in late April, about 10 days before revealing the ordeal to the public. Fritzl and Elisabeth were detained on April 26 near the hospital where Kerstin was being treated and Elisabeth then told her story to interrogators.
The letter is one part of evidence that authorities are using to piece together Josef Fritzl's double life.
One of the children she bore him died as an infant, and Fritzl has confessed to tossing the corpse into a furnace. He managed to smuggle the other three out to be raised by him and his wife, who was led to believe Elisabeth had given them up.
Police in Upper Austria are also examining whether Fritzl was also responsible for an unsolved murder in the nearby lakeside village of Mondsee two decades ago, where his wife owned an inn and camping ground.
The bound body of Martina Posch was found on a shore of the Upper Austrian lake of Mondsee on November 12, 1986. The wife of the incest suspect owned part of an inn and camping ground on the other side of the lake at that time and police are investigating a possible link because Fritzl could have been in the area at the "time and place" of the killing.
Fritzl faces up to 15 years in prison if convicted on rape charges. However, prosecutors say they are investigating whether he can be charged with "murder through failure to act" in connection with the infant's death. That is punishable by up to 20 years in prison.
Good grief! That man is absolutely a real sicko. I am soo glad that he is caught before he could even think about gassing them. He is a very very nasty and cruel man. It make me shudder to see his evil face and that video of him holidaying in Thailand. He should be execute.
