Callous Mentesh Da Silva, 19, crashed his black Renault Clio into a tree, instantly killing 18-year-old Emily Laker, after a witness said he appeared to be racing.
He was given a suspended prison sentence just three weeks ago after his lawyer told a judge he felt ‘extreme remorse and regret’.
But Da Silva, who admitted causing Emily’s death by careless driving, has now posted a message saying: “It was an accident s**t happens.
“I know she’s happier where she is right now compared to being in Canterbury round all them s**t heads.”
Da Silva sent the message to a friend of Emily’s family and it was circulated on social media by Emily’s mum Julie Swinerd with the caption “disgusting human”.
The yob, who was injured in the crash, previously outraged the family by posting a selfie from his hospital bed telling friends he was “still going strong”.
Emily’s father Ross Laker said: “Emily’s death has left a huge hole in our lives and caused us unimaginable pain and distress, which has only been made worse by the actions and words of the man responsible.
“While the sentence he received was grossly lenient, it was a relief to know that the court case was over and we were able to try and rebuild our lives, but he has not allowed us to do that.
“To say it’s ‘only up and forward’ for him just hours after he was sentenced was a kick in the teeth, but to now learn he has reduced my daughter’s death to ‘s**t happens’ and to say she is better off dead is truly disgusting.
“He convinced the court he was remorseful, but these are not the words of a man who has any comprehension of the pain he has caused.
“He has his whole life ahead of him while Emily had hers cruelly taken away by his actions.
“All we want is for him to let us move on and stop talking about Emily. It’s the least our family and her many friends deserve.”
Da Silva, who also goes by the name Mentesh Mouharrem, killed Emily after leaving a house party and collecting her from a pub where she had been working.
One witness described his Clio as “looking like it was racing” and told a court: “The driver had put his foot down and had gone for it.”
He was driving down a country lane near Broad Oak, Kent, in poor conditions on August 30 when he lost control and crashed.
Emily, from Sturry, Kent, died at the scene while Da Silva, from nearby Teynham, was taken to hospital. A third passenger escaped with minor injuries.
Judge Julian Smith gave him an eight-month prison sentence, suspended for 18 months, at Maidstone Crown Court on March 16.
Da Silva has not yet responded to a request for comment.
Emily Laker was planning to travel to Australia and work with the homeless before her tragic death.
The teenager was studying business at Canterbury College in Kent where she is thought to have met Da Silva who was also a student there.
She worked at the Tyler’s Kiln pub in Tyler Hill, Kent with her father’s partner Lisa Smart who is the bar manager.
Her dad Ross Laker, 49, lives with Lisa in Tankerton, Kent, and is the branch manager of a tyre depot.
At the time of her death, Emily was living with her mum Julie Swinerd, 45, and her 16-year-old sister Sophie in Sturry, Kent.
Emily, who also has an older sister, Louise, 23, spent her childhood growing up in Chilham, Kent, where she attended St Mary’s Primary School.
Mentesh Da Silva was banned from driving for two years and will have to take an extended test before returning to the road.
He was also subjected to a curfew from 7pm to 7am for four months and ordered to carry out 200 hours unpaid work.
Mentesh Da Silva refused to speak when he returned home from a day of community service yesterday (Thurs).
He was dropped off by a silver Mercedes outside his home in Welling, south east London.
He first attempted to run into the house next door before realising his error and sheepishly jogged to the correct front door.
Da Silva wore was wearing grey tracksuit with an open black body warmer and black trainers.
Shortly after he entered his home, his older brother, Serkan Ali-Osman, insisted that Mentesh didn’t mean what he said.
Serkan said: “He’s staying here because it’s the best place for him because there is someone there all the time.
“He’s going to stay away from the media, he’s going to stay away from the internet because I’m not having it.
“I got him to to shut down his Facebook and he’s now just trying to do his time.
“He’s just come back from his community service and he made sure he was home at the right time.
“I’m not going to talk about his comments. He has said it’s not what he meant.
“He’s been distraught and he still has nightmares about what happened.
“He’s not going to turn around and say ‘s**t happens’ in that sense.”
