A man who stabbed his girlfriend over 30 times during what has been called a "psychotic episode" has been cleared of her murder as he did not know "what was real and what was not".
Jake Notman attacked and ran over his girlfriend Lauren Bloomer, a 25-year-old university student, at their home in Tamworth, a trial at Stafford Crown Court was told. The 28-year-old car factory worker was cleared of her murder but pleaded guilty to manslaughter on Wednesday, mid-way through his trial.
Notman entered his guilty plea after prosecutors accepted psychiatric evidence - including analysis of a 17-minute mobile phone recording that was made by Miss Bloomer during the incident.
It was ruled that Notman was not in tune with reality and could not have formed the intent required to be classed as murder. Jack Notman was jailed for eight years and eight months on Wednesday.
Passing sentence, Mrs. Justice May said Notman had killed Miss Bloomer, a mature student at Nottingham University, in "the most unexpected and frightful way" during a two-and-a-half-minute attack.
The judge said: "I am quite sure that the psychotic state which Jake Notman was in was at least in part a response to the cannabis which he had taken."
She said the "obvious lesson" was "that cannabis can be very dangerous", adding: "It is an illegal drug for good reason."
The judge accepted that Notman, who had no previous convictions, had shown concern and remorse for the grief he had caused.
Jack Notman, of Bingley Avenue, Tamworth, was arrested by police in the early hours of Friday, November 20 last year.
At his trial, he denied murdering Miss Bloomer, claiming he had experienced an "extreme florid psychiatric episode" and had totally lost touch with reality.
The trial was told Miss Bloomer "recorded her own murder" on a mobile phone after seeking advice online about the "bad weed trip" suffered by her partner.
Opening the case last week, Deborah Gould, the prosecutor, told jurors that Miss Bloomer had activated her phone to record what was happening "like something out of the movie Scream".
Describing what could be seen or heard on the recording, which began when the couple were in a bedroom, Ms Gould told the court: "It shows the defendant as he began to attack Lauren Bloomer, at first with his bare hands.
"She was just trying to care for him in this state of being disordered through cannabis."
The jury heard that Notman became aggressive nine minutes into the recording, approximately one minute before Miss Bloomer was heard saying "please help me" to his aunt in a call on a second phone.
Notman, who worked at Jaguar Land Rover's site in Solihull, was seen by neighbours as he ran over his partner's body.
He then dialed 999 at 1.32 am, telling the operator he had "been told I have killed my girlfriend".
Notman made no comment in five police interviews, instead providing a statement suggesting the cannabis brownie - the first he had ever consumed - had something in it other than cannabis.
Explaining the Crown's decision to offer no evidence on the count of murder, Ben Douglas-Jones, the prosecution QC, said: "All three experts agree that on the evidence, including the recording, the defendant's psychiatric reaction to cannabis is of such profundity that he could not discern what was real and what was not.
"In particular he could not discern whether Lauren Bloomer was alive or dead, or real or not."
Commenting after the case, Mark Paul, of the Crown Prosecution Service, said: "It is impossible to comprehend how much Lauren Bloomer's family has suffered and will continue to suffer as a result of Lauren's completely unnecessary killing. My heartfelt condolences continue to be with them.
"Notman had ingested cannabis which led to a psychotic episode. Three forensic consultant psychiatrists concluded Notman had experienced a highly unusual type of psychosis at the time of the killing, which meant that he could not form the intention to commit murder, even the type of intention that can still be formed when a person has consumed drugs or alcohol.
"This expert advice meant there was no longer a realistic chance of conviction for murder, and Notman has now accepted responsibility for the unlawful killing of Lauren Bloomer by entering a guilty plea to manslaughter.
"We fully explained to Lauren's family why the murder charge could not be pursued."
Miss Bloomer's family said in a statement: "As Lauren's family, we feel that regardless of the outcome of the trial, nothing can bring Lauren back to us or compensate for the heartache we feel.
