Two brothers who killed four people in a crash while on the run from police have been jailed for over 20 years.
Elliott Bower, who was driving the car was sentenced to 11 and a half years' detention while his brother Declan and passenger Mason Cartledge were jailed to seven years and eight months each.
The judge told Elliott Bower he would have been given the maximum 14 years if he had not pleaded guilty.
Two "wanted" brothers taunted police on social media before leading officers on a high-speed chase in a stolen car resulting in a crash that killed four innocent people.
Driver Elliott crashed into a people carrier containing seven people as he drove a Volkswagen Golf through areas of Sheffield at speeds in excess of 100mph to evade the police.
The driver of the people carrier, Adnan Ashraf Jarral, 35, died along with his 16-month-old son, Muhammed Usman Bin Adnan, and a married couple, Vlasta Dunova, 41, and Miroslav Duna, 50.
Elliott Bower and his brother Declan were wanted by police for questioning in relation to serious offences at the time of the crash in November.
Richard Wright QC, prosecuting, said the pair, along with another teenager, Mason Cartledge, now 18, were all engaged in a "pro-criminal lifestyle" and were "resolved not to surrender to custody".
Mr Wright said that, in the days before the fatal crash, the brothers posted a picture of themselves on social media in a "deliberate and gratuitous taunt" to police.
The court heard the picture showed the two men "grinning inanely", with Elliott Bower holding up his middle finger and with the caption "f*** da police".
to aggravated vehicle taking in which death was caused.
On the evening of the crash, the three defendants were travelling in the Golf, which they had stolen and fitted with number plates cloned from another car to avoid attracting the attention of police.
When they were identified by officers, Elliott led their marked vehicle on a five-minute chase over nearly six miles, during which he reached speeds in excess of 100mph, drove on the wrong side of the road on a blind bend and drove the wrong way around a roundabout.
The chase only ended when the Golf ploughed into the Volkswagen Touran, driven by Mr Jarral, at a speed of 79mph, instantly killing four of the people in the car.
Elliott Bower and Cartledge left the car in an attempt to run away but were detained at the scene.
Emergency services found Declan Bower, who was trapped in the car with a broken leg and wrist, "seemingly unconcerned by the severity of the collision" and "casually smoking a cigarette".
The Touran contained members of two different families who had travelled from London to Sheffield and were just yards from home when the collision occurred as Mr Jarral was turning right on to a residential street.
Mr Wright said there was "virtually nothing left" of the driver's seat or rear passenger seat in the Touran following the collision, the force of which drove the people carrier 33m along the road. Mr Jarral and three rear seat passengers were killed instantaneously.
The three survivors, Mr Jarral's wife, Erica Kroscenova, the fatally injured couple's daughter, Nikola Dunova, 22, and her three-year-old daughter, Livia Matova, were all seriously injured.
When he was arrested, Elliott Bower, who, at the time, was subject of a warrant issued for failing to appear at court for breaching a suspended sentence for burglary, told police he was not the driver.
He told arresting officers: "You can remand me if you like, I'll get out and I'll do bang the same thing again and you lot will have to chase me."
