Questions need to be asked over the police response to a car crash tragedy, a former Welsh crime commissioner has warned - and said "alarm bells" should have rung when five young people went missing.
Eve Smith and Darcy Ross, both 21, and Rafel Jeanne, 24, died in the collision, while Sophie Russon, 20, and Shane Loughlin, 32, remain in a critical condition after a Volkswagen Tiguan they were in left the A48(M) in Cardiff and hit trees in the St Mellons area of the city.
Officers believe the car was involved in a collision and left the road some time later, but further investigations are needed to establish an exact time.
