Now, months on from her disappearance, court documents have revealed disturbing text messages between the couple, and Bennett has been accused of killing his wife.
According to The Times, the couple fought extensively prior to the alleged honeymoon murder.
“This morning I was afraid to get home with the coffee but I walked in and I was right,” one text message from Hellmann read. “I found an angry person, this is very sad.”
“Sometimes I can be a pain in the a-s and more but you need to change your attitude… you make me crazy shouting, yelling, swearing… YOU ARE PUSHING ME AWAY,” read another.
“If you don’t like me or love me anymore let us fix this asap because is very pathetic the way you treated me all the time,” said another.
Bennett, 41, told authorities that he was below deck when he was jolted awake by what felt like a collision in May 2017, after which he jumped onto a lifeboat, with his Colombian born wife nowhere to be seen.
According to the Gold Coast Bulletin, Bennett then contacted a friend on the Gold Coast and the friend, in turn, alerted the Australian Maritime Safety Authority, who passed the message onto the US Coast Guard.
