Nine of the women who were seduced by a con man who lied about his identity and swindled his smitten lovers out of $2million have broken their silence.

Derek Alldred, 49, met more than two dozen women online, faked his identity with a web of lies, then quietly stole their credit cards, their Social Security numbers, and with some, spent their entire retirement savings.

Several of his victims are finally speaking out and revealing their heartbreak and terror upon realizing that their lover was really a con mastermind in the new documentary Seduced by Evil, set to air on Oxygen on Saturday.

'Derek took everything from me...$325,000,' Linda Dyas, who reported Alldred to police, says in the documentary.

The women revealed they all thought they had found their true love with Alldred.

'He was the perfect guy... I thought he was the one...mother's day four dozen roses,' several of his victims explain in the documentary.

He even made big plans with his victims like moving in together and making wedding plans.

He specifically targeted intelligent and vulnerable women seeking a long-term partner so he could benefit from their money.

Cindi Pardini met Alldred in 2012 through mutual friends on Facebook but would not meet in person until September 2013, He asked to stay at her home, presenting himself as an investment banker hoping to relocate from Hawaii to San Francisco. He ultimately scammed the woman out of $250,000 by hacking into her finances.

Alldred then met Wendy Harvey on a dating website as Derek 'Allred.' The man claimed to be an investment banker and bought the Maui agency CEO lavish gifts, including $3,000 diamond earrings. While she began having suspicions about him while doing online searches, those worries were confirmed after Pardini called and revealed that Alldred was using her money to buy Harvey gifts.

Alldred met Dr. Kimberly Haycraft on Match.com in 2013 after he had left Pardini. Haycraft owned anti-aging practices in Maui and Minnesota, while Alldred claimed that he was part owner in a financial firm and became her business manager when the two started getting serious. He robbed her of $35,000 in fraudulent checks, $60,000 in fraudulent credit and a $28,000 advance. Haycraft eventually bankrupted her businesses and feared for her life with Alldred, which was covered in 'Seduced By Evil.'

Next, he claimed to be 'Derek R. Allarad' when meeting Minnesota school teacher JoAnn Venhuizen on Match.com in 2014. Alldred claimed to be an international banking lawyer but Venhuizen sensed something was off when they went on a trip to Hawaii to meet his daughter that never showed. The teacher would soon learn that there was a warrant out for Alldred's arrest but not before he managed to steal $24,000 from her.

Alldred met Minneapolis IT executive Kimberly Nelson on OurTime.com while dating Dyas, going by the name 'Rich Peterson.' He claimed to be a professor who was volunteering at a homeless shelter and the two dated briefly before breaking up and rekindling the flame in 2016. She soon learned that he stole $8,000 worth of jewelry, her passport and even her birth certificate. Nelson would soon learn that Allred was sleeping at that same shelter.

The mastermind would meet Dorie Watkins, a HR manager from Dallas, on PlentyOfFish in mid-2017. He claimed to be an employee with Department of Defense named 'Rich Tailor who worked as a Navy jet pilot. But Watkins became suspicious when he kept cancelling on him and by the time she realized who he could be, Alldred had already stolen $17,000 from her. The woman would take his fake uniform and badge to her local police.

Alldred also dated Dallas health care executive Tracie Cooper-Cunningham on PlentyOfFish at the same time he was dating Watkins. He went by 'Rich Tailor' on a different profile and old her he was a 'semi-retired' political science professor who served in the Navy. When she finally tried to end their fling after a month and a half, she received a call from Naval Criminal Investigative Service and participated in a sting to help detain him.

His scam finally began falling apart in spring 2016 after he met former flight attendant Missi Brandt.

Allred met her under the alias Richie Peterson off dating website OurTime.com and lied that he completed eight tours in Afghanistan and even donned a full uniform when he spent time with Brandt and her daughters.

One day when he was in the shower, she went through his wallet and found a Social Security card with his real name and two credit cards belonging to another woman - Linda Dyas.

Brandt investigated Alldred and immediately contact Dyas.

'I was contacted on Facebook Messenger by another victim who sent me his real name and his prior arrest and an article on him with his mugshot,' Dyas, a nuclear scientist based in Minnesota said to Fox.

'It was just a huge shock. I mean, yes, I was questioning, but when you think somebody might have lied to you about some things, you don’t think they lied about everything. It was literally about everything,' she added.

Allred and Dyas were living together in her home at the time.

'He was still in my house at the time. I was upstairs in my bedroom when I opened this message,' she said. She immediately went to go check on her gun which she kept in the house and found it missing.

He also paraded as an army veteran who did eight tours in Afghanistan

'He had used it a time or two at the shooting range. I found out later that he had carried it with him at times. I had told him not to use it. I planned to change the safe lock, and I didn't,' she said.

'There I was upstairs in my bedroom scared out of my wits because I just saw this guy's mugshot,' she added.

Dyas added there were warning signs.

'His military career didn’t really match up. But I didn’t question it that much. He had told me he was a reservist. I didn’t really know anything about that. I didn’t ask the questions I probably should have. But I just never pushed the issue,' she said.

On another occasion he threw a violent and angry outburst that terrified Dyas.

He conned more than two dozen women out of a cumulative $2million and was sentenced to 24 years in prison for his crime s

'It was about seven months into the relationship. He got angry about something. I don’t even remember what it was. But the way he handled it was out of what I would think was the norm. He really went over the top. It scared me. To be honest, it put the fear of God in me. … Very soon after, I was getting feelings that something wasn’t right,' Dyas said to Fox.

Later that same day Alldred complained of a pain and said he needed to go to the emergency room.

Dyas dropped him off them called the cops on her way home. By the time she called Brandt to tell her the news, Alldred was already in custody.

Alldred stole all of Dyas' emergency credit cards, ordered new cards in her name and maxed them out on lavish dinners and trips to Hawaii with her and other women.

He drained her retirement savings and used the money to purchase a boat, two motorcycles and he even put her name on the house's lease.

Dyas and Brandt then launched their own investigation and met other women who were also conned by Alldred.

It turned out Alldred had used various aliases and pretended he had an impressive career alternating between a US Navy pilot, professor, defense analyst, attorney, doctor and firefighter.

In August Alldred was sentenced to 24 years in prison in Texas for his crimes. He pleaded guilty to mail fraud and aggravated identity fraud and was forced to pay $255,000 in restitution.

Prosecutors determined he targeted at least 25 women in California, Hawaii, Minnesota and Nevada.

'This defendant left a trail of tears, emotional devastation, and financial ruin behind him,' US Attorney Joseph Brown said at his sentencing.

Cindi Pardini of San Francisco rallied the victims up to bring Alldred to justice, according to the US Attorney's Office in Texas, and nine of them spoke at Alldred's sentencing.
