Wakefield quad bike crash victim Ryan Beal was just two days away from his 21st birthday when he was killed in a crash with a Nissan sports car on the A6201 on 27 September. Two men and two teenage women died in the horror smash in the early hours of Sunday morning in West Yorkshire.
Local sources have named Beal as the 20-year-old who died at the scene while Brandon Brown has been named as the man who later died at Leeds General Infirmary. Two females aged 16 and 18 were also pronounced dead at the scene. West Yorkshire Police arrested two men - aged 21 and 22 - on suspicion of dangerous driving.
Tributes have been paid to the victims on Twitter:
Detective Chief Inspector Richard Holmes from the Homicide and Major Enquiry Team said: "Widespread investigations are continuing into what is a significant incident on the district's roads which has now tragically resulted in the loss of four lives.
"Painstaking investigative work is continuing at the scene and the road itself will not be reopened until tomorrow. The victims are from the local area and are two men aged 20 and two females aged 18 and 16. Their families are currently being supported by specially trained officers and we are not in a position to release any further details of those who have lost their lives at this time."
He added the force was appealing for witnesses and would also like to speak to anyone who may have seen a unregistered quad bike driven on the roads around the Hemsworth area on 26 September and up to 0.30am the next day. Police would also like to hear from anyone who saw a bronze-coloured Nissan 350Z driven in the Hemsworth area during the same period.
