Homicide detectives have charged a man with murder after a man was found dead and a woman suffered serious head injuries at a home north of Brisbane.
Police were called to do a welfare check at a Burpengary East home on Thursday morning where they found two people in their 70s with serious head injuries.
The man was declared dead at the scene while the 71-year-old woman was rushed to hospital in a life-threatening condition.
The woman remained in the Royal Brisbane and Women's Hospital in a critical condition on Thursday night.
A 26-year-old Beachmere man was taken into custody after he waited at the property for police.
Police charged the man on Thursday night with one count of murder and one count of attempted murder.
He was refused police bail to appear in Pine Rivers Magistrates Court on Friday.
Detective Inspector David Harbison said it was not a domestic violence-related incident and the 26-year-old man was not previously known to the victims.
"We believe he just attended today to do some form of gardening duties," Det Insp Harbison told reporters on Thursday.
Police are not looking for any other persons of interest.
Det Insp Harbison described it as a tragic and devastating incident.
"It is so terribly traumatic for anyone to see this, including first responders," he said.
"We hope to get to the bottom of it and learn more and try and understand how this incident occurred."
