A three-month-old baby has died after a car crash in Perth’s southern suburbs, which also seriously injured two adults.
Police are investigating whether speed was a factor in the crash, which occurred on the Kwinana Freeway in Baldivis shortly before midnight on Friday night.
The three-month-old boy was taken to Princess Margaret Hospital, but died within a few hours.
The two adults who were in the car — a 20-year-old man and an 18-year-old woman — are in a serious but stable condition in hospital.
It is understood they are the baby’s parents.
The car, a maroon sedan, is believed to have rolled before striking a lamp post, with the infant and both adults flung from the vehicle.
Police said a car matching the description of the one involved in the single-vehicle crash was spotted driving erratically shortly beforehand.
