A Spanish-Mexican woman is serving a life sentence in a mental institution in Austria for the "ice cream murders" - the 2008 murder of her husband and the 2010 murder of her lover.

Estibaliz Carranza took the time in prison to pen her memoires "My Two Lives, The True Story of the Ice Lady" in which she tells about shooting her husband Holger Holz while he sat in front of the computer, and then killing her lover, Manfred Hinterberger, while he slept, according to BBC.

The "Ice Killer" used a chainsaw to decapitate and dismember her victims, according to BBC. She cemented the body parts in flower pots and hid them in the basement of her ice cream parlor.

"I don't ask for understanding or for pardon," Carranza wrote in her book, co -written with journalist Martina Prewein, according to BBC.

"I killed two men, whom I once loved," Carranza wrote, according to BBC."There is no way of glossing this over. I robbed two mothers of their sons."

"I believed I had to serve men, no matter how they behaved towards me," she wrote, according to BBC.

Bernhard Salomon, Carranza's publisher, told the BBC the murderess "waived her right to a fee for the sake of the relatives."

There has been no comment from the victims' families. The book is to be published on Monday.

The book opens in 2011 when Carranza finds out she is pregnant by a third man, according to BBC. Carranza since married the father of her child while she was in prison.

Adelheid Kastner, court psychiatrist during her 2012 trial, said there was "a higher than average chance" Carranza would kill again, according to BBC.
