THE final months of Shana Grice's life were characterised by violence and threats at the hands of controlling former boyfriend Michael Lane, compounded by Sussex Police's failure to properly investigate her claims.

She was later fined for wasting police time.

By the end of the summer, she was dead.

A judge later said police "jumped to conclusions" and "stereotyped" Miss Grice, while her family said the murder could have been prevented if officers had taken the teenager's complaints seriously.

Here is a timeline of the incidents surrounding the case:

February 8 2016: Shana Grice first reports Michael Lane to police for stalking her, sending her unwanted flowers and leaving a message on the car of her boyfriend, Ashley Cooke.

March 24: Police are called after Lane pulls Miss Grice's hair and tries to grab her mobile phone.

No further action is taken against him.

But Miss Grice is issued with a £90 fixed penalty notice for failing to disclose that she had been in a relationship with Lane, and for "having caused wasteful employment of police by making a false report".

July 9 : Lane is cautioned by police and told to stay away from Miss Grice after he steals a back door key from her home and lets himself in.

He watches her sleeping before leaving.

July 10: Miss Grice reports to police that she has received around seven calls from a withheld number, including one with heavy breathing, which she believes is related to the incident the day before.

She is told that there are no further lines of inquiry and that the case will be left on file.

July 12: Miss Grice reports to police that she has been followed by Lane.

August 23: Miss Grice meets Lane at a hotel in Hove where she confirms their relationship is over, though Lane refuses to accept it.

August 25: Lane enters Miss Grice's bungalow in Brighton, slashes her throat, and sets fire to her bedroom.

March 22 2017: Jurors at Lewes Crown Court find Lane guilty of murder following a two-week trial.

He is subsequently jailed for life with a minimum term of 25 years.
