The teenager, who cannot be identified, is in custody charged with murdering Kate Leadbetter, 31, and Matthew Field, 37, who were walking their dogs in Alexandra Hills, southeast of Brisbane.

Leadbetter was six months’ pregnant at the time.

Media – who were previously refused access to court proceedings – were allowed to remain in the Brisbane Children’s Court when the matter was mentioned on Tuesday.

Police allege the 17-year-old Logan boy ran a red light in a Landcruiser and collided with a truck at an intersection before the 4WD rolled and ploughed into the couple who were crossing the road.

They both died at the scene and it’s alleged the teen fled before stealing a set of keys from a nearby house.

He was then arrested by police after being disturbed by the resident.

Police believe the Landcruiser was stolen from a home in Cleveland earlier that afternoon.

The 17-year-old was charged with two counts of murder as well as offences relating to dangerous driving while under the influence of an intoxicant, failing to fulfil duties at the scene of a crash, wilful damage and burglary.

Defence barrister Ruth O’Gorman asked for the case to be adjourned for five weeks, saying they had received close to a full brief of evidence.

Magistrate Anne Thacker remanded the teenager in custody to appear by video-link, if necessary, when the matter is mentioned in the same court on August 5.
