A 26-year-old has been taken into custody after a man in his 70s was found dead at a home north of Brisbane this morning.
Police arrived at the house on Bramston Court in Burpengary East at 9:20am to conduct a welfare check when they found the body of Nicholas Reeves.
His wife, Suzanne Reeves, also in her 70s, was taken to the Royal Brisbane Hospital with "significant injuries to the head", Detective Inspector David Harbison said.
The 26-year-old man was believed to be gardening at the house next door when an argument allegedly broke out, he added.
"Unfortunately, the victims have been severely injured, one fatally," Detective Inspector Harbison said.
"Police are still investigating if an implement or weapons were used in this incident … we don't have the full facts yet."
Police said the man was onsite when police arrived and was taken into custody without incident.
Detective Inspector Harbison said he was not known to the victims, adding that it was not a domestic violence incident.
The house next door has also been declared a crime scene, and police are urging witnesses or anyone with dashcam footage to contact police.
