Shocking CCTV footage shows missing American tourist Robyn Gardner having a violent fight with her travel companion hours before her disappearance in Aruba, it has been reported.
Prime murder suspect Gary Giordano, who friends said she met on a swingers sex site, is thought to have threatened to kill her while grabbing her by the neck and shoving her into an elevator on August 2 - the last day Miss Gardner, 35, was seen alive.
Mr Giordano, a 50-year-old businessman from Maryland, travelled to Aruba with Miss Gardner on July 31 and reported her missing two days later, saying she disappeared while they were snorkelling. He has not been charged but is being questioned in jail after witnesses said he was sweating profusely on that day, with blood next to him on the beach and a large scratch mark on his throat.
Mr Giordano initially assisted the search but was detained at the airport as he tried to leave the country because of questions about his account of what happened.
The videotape from the Marriott Resort in Aruba allegedly shows the two having a furious and violent fight on the day she went missing.
A source close to the investigation told the National Enquirer: 'They were having a major fight. Robyn was waving her arms and shouting at Giordano. He was grabbing her arms and jerking her around and shouting back at her.
'Then Giordano apparently realised their argument was heating up in public where someone might overhear them. He violently grabbed the back of Robyn's neck with one hand and shoved her back into the elevator with the other hand.'
As Mr Giordano faces a court hearing today to determine whether he can be held without charge in jail for another 60 days of questioning, police in Aruba believe the CCTV footage is what they need to keep him detained.
'Aruban authorities believe those few, crucial seconds of video tape will give them what they need to put Gary Giordano in prison for life,' the source added.
The tapes are now said to have been sent to the FBI and to surveillance experts in Holland for further analysis.
The source said lip-readers believe Robyn was shouting at Mr Giordano: 'I'm out of here. I'm leaving. I'm not spending another minute with you,' while he yelled back: 'Get back here! I'll kill you!'
There is also a suggestion he might have drugged her when she refused to have sex with her, sources told the Enquirer.
Meanwhile, one of Miss Gardner's friends told police the pair met on Adult Friend Finder - a site which describes itself as 'the world's largest sex and swinger personals community', according to ABC News.
Witness statements also revealed that the pair had planned a holiday together before but Miss Gardner had backed out because of his 'scary behaviour'.
