Concise News reports that Ronnakorn Romruen, 24, has confessed to smashing the head and face of Miriam Beelte with a rock after subjecting her to the vicious sex attack.
Romruen attacked the 26-year-old after she arrived on the idyllic island of Koh Si Chang, eastern Thailand, on Sunday.
He pestered her for sex but when she refused, he told police he followed her into woodland and raped her.
Romruen was arrested a few hours later. He confessed to police he murdered Miss Beelte by repeatedly hitting her in the face with a rock to stop her from reporting the attack.
He then tried to hide the blood-spattered body under leaves in a small gap between rocks.
At a police conference in Chonburi province on Monday afternoon, Ronnakornwore with a blue bag over his head was paraded to the public.
A police worker laid on the ground as Ronnakorn demonstrated with a brick how he battered Miriam’s face.
He told police that he had taken methamphetamine at the time of the attack.
He then returned home and washed his clothes in a bid to hide the evidence.
Miriam was found a few hours after the attack by a local resident. The island was then sealed off by police.
Speaking on Wednesday, Police Colonel Angkul Sarakul says in the video that Ronnakorn had confessed to the murder.
He says: “This is how he did it. This is how he killed the tourist. He used a rock to hit her in the face.”
Police Colonel Sarakul says Ronnakorn would be charged with premeditated murder, rape and concealing a body.
He has been detained at the Chonburi Police Station while officers prepare legal paperwork for him to be submitted to the court.

“Police were very quick to catch him. We were able to trace him as he was very near to where he killed the tourist.”
