The newspaper identified Aminah as Irena Horak, 35, who had previously worked in a care home in Zagreb and had converted to Islam in 2008, and it posted several pictures of her.
The paper reported -- according to close friends -- Horak, a cheery athletic blonde from a small town in central Croatia converted to Islam after falling in love with a Muslim lawyer from London she met at a wedding in summer 2008. Horak had been brought up Catholic.
The two started a long-distance relationship, but after throwing herself into her new religion, Horak came to feel her boyfriend was not sufficiently devout because he drank alcohol and failed to wake up for morning prayers. That resulted in her leaving him, according to the newspaper.
"She changed her life habits completely and way of dressing," and spent all her time in the mosque one friend told the newspaper.
"She was looking for someone more radical and found him in al-Awlaki," the newspaper reported.
Family and friends of Horak told Vecernji List they had been shocked by the news that she had traveled to Yemen to marry al-Awlaki. She had told them she was going overseas for language study.
Storm told Jyllands-Posten he first came into contact with Aminah, the Croatian convert, in late 2009 through Facebook, and that she soon warmed to the idea of marrying al-Awlaki.
At a meeting in Vienna in spring 2010, Storm showed Aminah a short video recording made by al-Awlaki, who was dressed in white robes in front of a pink background with a floral motif.
"This recording is done specifically for Sister Aminah at her request ... I pray Allah guides to that which is best for you in this life and in the hereafter. And guides you to choose what is better for you regarding this proposal," al-Awlaki said, in a section posted on the Jyllands-Posten website.
Storm said Aminah burst into tears when she heard these words.
She then recorded two short videos for al-Awlaki. In the first video, she wore a full black veil with just her face visible. Speaking in heavily accented English, she said: "I will accept everything that is needed to do now this way that I have chosen and Inshallah Allah will help us."
In the second video, Aminah took off her veil and said: "Brother, it's me without the scarf, so you can see my hair ... I hope you are happy with me, Inshallah," according to Jyllands-Posten.
"When I watched these tapes of video marriage proposals between her and the al Qaeda leader, and this woman's answers, I thought well this story is impossible to deny," Collignon, the editor of Jyllands-Posten, told CNN. The Vecernji List report appears to further buttress Storm's account.
Aminah and al-Awlaki married shortly after Aminah arrived in Yemen in June 2010. Al-Awlaki sent Storm a message thanking him for arranging the marriage. She had not only lived up to expectations, al-Awlaki wrote in a message seen by Jyllands-Posten, but was ".... much better!"
After al-Awlaki's death in September 2011, Aminah continued to communicate with Storm through encrypted messages, unaware that he had been working with Western intelligence. A few months ago, she said she was working on Inspire, the online magazine of al Qaeda in the Arabian Peninsula, or AQAP.
She also suggested she wanted to be involved in a terrorist attack, according to Jyllands-Posten.
"I would be making a martyr operation, but Sheikh Basir (al Wuhayshi, the emir of AQAP) said that the sisters so far (can) not carry out operations because it will mean a lot of problems for them ... so I can not perform operation. ... I want to be killed the same way as my husband was ... Insha'Allah," she wrote.
Aminah's whereabouts today are unknown. CNN has been in touch with Storm, who is in hiding after several death threats from militant Islamists who were once his comrades.
