Two young men were killed and two others critically injured when their car crashed into two parked vehicles, police have said.
One of the victims, aged 23, was pronounced dead at the scene of the accident in Walsall, West Midlands, while an 18-year-old man died shortly after arriving at Birmingham's Queen Elizabeth Hospital.
Traffic officers said two other men, in their late teens, were taken to hospital after the Subaru Impreza smashed into two stationary cars at about 9pm on Tuesday night.
Sergeant Ferris Hatheson, from the West Midlands Police collision investigation unit, is seeking witnesses to the accident, which happened at the junction of Brockhurst Crescent and West Bromwich Road, in the Delves area of Walsall.
Sgt Hatheson said: "Two young lads have lost their lives in this collision and their relatives and friends are obviously shocked and devastated by last night's events.
"We appeal for any witnesses who were in the area or who may have seen the car travelling in the vicinity to come forward and help the investigation.
"In particular, we are keen to hear from the occupants of a small hatchback car that is believed to have been travelling along the road around the time of the collision.
"The people inside this vehicle are likely to have information that may prove significant to our investigation."
Anyone with information to help the investigation is urged to contact the collision investigation unit at Birmingham's Aston police station on 0345 113 5000.
