Hotel worker who stabbed a 16-year-old girl  to death in a frenzied sex attack after luring her to a hotel with the promise  of a job was jailed for a minimum of 35 years today,

David Minto, 22, who nicknamed himself ‘The  Demon’, used Facebook to entice young  women to the seaside B&B where he lived and worked.

When Sasha Marsden arrived after being told a  job was available, Minto pounced on her and then stabbed her 58 times in the  head, face and neck with a kitchen knife when she tried to run away.

The court heard he had sexually  defiled her as she lay dying or was already dead.

Minto, who was a caretaker and barman at the  hotel, wrapped her body in a bin bag, carpet and duvet before  dumping it an  alleyway and setting it on fire.

Police who found her body thought at first it  was a tailor’s dummy which had been set alight.

The college student, from Staining, near  Blackpool, could only be identified by DNA from her toothbrush.

Today Minto was branded a ‘real life Norman  Bates’ after he was convicted of murder at Preston Crown Court.

He was jailed for life by Judge Anthony  Russell QC who told him he had killed Sasha in a ‘brutal fashion’.

Minto was a drifter had only got a job thanks  to his long-time girlfriend Rachel Butterworth, whose mother owned the  Grafton House Hotel in Kirby  Road, Blackpool.

The court heard he was a ‘sexual  predator’  who had a fascination with violent movies like Scarface and  Resident Evil and  trawled social media sites looking for women to lure  back to the B&B whilst  his unsuspecting girlfriend was out.

Kimberley Fazackerly, 22, told how  she was  ‘frightened and scared’ after Minto pounced on her after she  agreed to visit  the premisis following a series of text and Facebook  messages.

Miss Fazackerly said: ‘In 2012, David got in  contact on Facebook and he said he had a hotel in Blackpool. He  said he ran it  with his girlfriend Rachel and her mum. He said he owned  the hotel.

‘I did visit the hotel on one  occasion and  David gave me a tour showing me the bar, his and Rachel’s  room, Rachel’s mum’s  room and Rachel’s brother’s room. After that we  went into Rachel and David’s  room and sat on the bed. I felt scared as I could feel something was going to  happen.’

She told the court Minto touched her  inappropriately. ‘I told him to get off but he didn’t get off straight away,’  she said.

‘I told him again and he got the message. I  was very frightened. I left and went straight home.’

Miss Fazackerly said after the  incident in  the hotel she never went back and she ignored any further  messages from Minto  on Facebook.

On January 27 – four days before her death –  Minto contacted Sasha on Facebook using his nickname David ‘Demon’  Minto.

He talked about the prospect of a  cleaning  job at the hotel to ‘arouse her interest in meeting him’ even  though he did not  have the authority or money to offer her job.

He also kept his contact with Sasha  as a  ‘complete and total secret’ from his girlfriend and arranged his  meeting whilst  Rachel was out.

Sasha – a child care student at the  Blackpool and The Fylde College – got a lift from her father to the  hotel at  4pm on January 31.

Three hours later a neighbour spotted smoke  and flames in the L-shaped alleyway by the hotel and doused the  flames with a  bucket of water – unaware there was a body on fire.

By 8pm, Sasha’s parents Jane and Gary had  become anxious about their daughter and went to the hotel where  they met Minto.  He told them she had left hours earlier.

Examinations revealed Sasha had  suffered  ‘terrible and catastrophic’ injuries as she ‘struggled  ferociously’ in a vain  attempt to fend off the ‘sexually motivated’  killer.

Forensic tests showed the teenager’s  blood  was found on the defendant’s clothing, throughout the hotel and on the murder  weapon.

Her blood-stained Adidas top, shoes,  purse  and mobile phone were found in a wheelie bin. Her mobile phone had been  dismantled and the battery removed.

When police searched a bathroom at  the hotel  later they discovered someone had tried to flush Sasha’s  jewellery and earrings  down the toilet and her DNA was found in the  bath.

Minto was arrested on January 31 and  went on  to tell ‘a series of lies’ to hide his involvement, including a  claim that  Sasha had ‘thrown herself’ at him sexually.

He told a jury at Preston Crown  Court that  he last saw her leaving the hotel and she must have returned  while he was  upstairs and met her death at the hands of a mystery  assailant.

He did admit moving the body in a state of  shock but did not set her alight, he claimed.

His version of events was rejected by the  jury after less than three hours of deliberation.
