The man accused of murdering American biologist Suzanne Eaton in Crete earlier this month was seen being marched towards Greek prosecutors in handcuffs on Tuesday a day after confessing to her killing.

Yiannis Paraskakis is a local farmer, priest's son and father-of-two who is said to have told authorities that he hit Dr. Eaton with his car on July 2 then stabbed her in a 'sexually motivated' killing.

Her body was found hidden in a Nazi bunker in the hills near Chania. She had been stabbed, suffocated and one of her ears had been cut off.

In his confession, Paraskakis told investigators that he hit Dr. Eaton with his car twice.

He then carried, while she was unconscious, into the trunk of his car and drove to the bunker where he said he raped her and then killed her.

The 59-year-old scientist fought her attacker off and she had DNA under her fingernails when she was found a week after vanishing.

Police say she had many broken ribs, facial bones, and multiple injuries to both hands.

Detectives were led to the suspect after interviewing a group of people they said knew the tunnel network well.

Some included neo-Nazis.

Constantinos Lagoudakis, a senior police official in the Cretan town of Chania, said in a televised statement on Tuesday morning: 'During the questioning he confessed his act and will be taken to court today.'

Paraskakis is active on social media and YouTube where he has shared photos and videos of himself inside what look like the same caves where the doctor's body was found.

Eaton was a mother-of-two who was in Greece to attend a conference. She was a California native who lived in Germany with her British husband.

On July 2, she had ventured out for an afternoon walk when she was attacked and killed.

Her body was found a week later in a state of decay.

Paraskakis is expected to be charged with murder on Tuesday.

Police said on Tuesday that he was arrested after they discovered tire tracks near the tunnel.

'A particularly important element of our investigation was the discovery of recent tyre tracks near the (tunnel).

'This, in conjunction with the position of the body when it was found, suggested that it had been transferred to the site,' Lt Gen Lagoudakis said.

Police Major Eleni Papathanasiou, a spokeswoman for Crete police, gave more details of the harrowing crime.

'The suspect reported that on July 2 2019 … motivated by the intention to commit sexual assault, he hit her twice with his car to stop her,' she said.

'According to his claims, he placed the victim, unconscious, in the boot of his car and transferred her to a ventilation drain in the wartime storage (tunnel), where after raping her, abandoned her there.'

Local villagers said they believed only somebody from the area would have known about the cave, which is off a dust track and then involves a trek through rugged woodland and is not visible easily to the naked eye or from the road

Dr. Eaton's family paid heartfelt tributes to her earlier in the week.

Her mother, son Max, brother Rob and her sister have broken their silence to remember the 59-year-old scientist who was suffocated and stabbed after going out walking.

Her mother Glynda said: ‘She was a devoted wife and mother, and dearly loved by her family.

‘From the day Suzanne was brought to me right after she was born - stuffed into a red Christmas stocking, December 23 - not drowsy and sleepy but with her head up, her eyes alert, that interest in everything around her has never changed.

‘It has been a joy to share her love of books and music, to observe the combination of a certain flamboyancy with a calm, thoughtful, steady personality.

‘Her accomplishments are many and varied: avid gardener, accomplished pianist, black belt in Taekwondo, and of course her contributions to developmental biology.’

One of her two sons Max added that he would always ‘cherish’ her memory.

He added: ‘My mother was a remarkable woman.

Dr Eaton left the Orthodox academy for a run and was discovered in a World War II cave near the settlement of Xamoudochori on Monday nigh

‘She managed to live a life with few regrets, balancing out her personal life with her career.

‘I think the fact that I did not realize how well she had managed to do so was evident that other mothers around me had taken to caring for their children full time, yet mine was never outdone by any of them.

‘Supportive and encouraging, she nurtured and supported anything that the distractible mind of my childhood would come up with, and this curiosity has stuck with me to this day.

‘As I grew, her brilliance as a scientist began to dawn on me. Always armed with a question, she would show interest in any topic broached.

‘Many a time I discussed topics with her that I had studied at university, and within a week, she would be as well versed in that topic as any of my professors.

‘Yet she was far more than a scientist. Her love for music shone brightly, her eyes lit up every time she talked about a piece she was playing, and she would laugh with me in admiration of the sheer complexity of a piano arrangement.

‘I have many fond memories of her and my father playing duets together, filling our home with a beautiful, joyful sound that was unique to them, and I shall forever cherish the memory of lying on the floor, watching and listening to the thing that brought them together.’
