A 29-year-old man has been charged with murdering his own twin brother after police discovered the victim’s body in the backyard of their shared home in Australia, leaving relatives devastated and investigators searching for answers.
Ashley Bruno Grillo was arrested after officers made the disturbing discovery Thursday, October 8, at a residence in Orelia, a suburb of Perth in Western Australia.
The victim, also 29, was found with visible injuries in the backyard of the property, where investigators believe his body may have remained for several days before authorities were alerted.
The case has taken an especially troubling turn after police revealed that the suspect and victim were identical-age twin brothers who had been living together at the home.
Investigators are treating the death as a suspected family violence homicide, while forensic specialists examine several bladed objects recovered from the property.
The investigation began around 2:20 p.m. Thursday when a concerned family member visited the residence on Nye Way and contacted police.
Authorities have not disclosed exactly what prompted the relative’s concerns, but officers were dispatched to investigate the situation.
When police arrived, they discovered the body of a 29-year-old man in the backyard.
His twin brother was located at the property and immediately taken into custody.
The Western Australia Police Force’s Homicide Squad was called in to investigate, and the normally quiet residential street was quickly transformed into a major crime scene.
Detectives, forensic specialists and other investigators spent hours searching the house and surrounding property for evidence.
Officers also examined an area of disturbed soil in the backyard, raising questions about whether the victim’s remains had been concealed.
Local media reported that the body may have been partially buried, although police have not officially confirmed that detail.
Authorities have also not established publicly how long the victim had been dead before officers arrived.
During a news conference Friday, Acting Detective Superintendent Jessica Securo confirmed that the deceased man had suffered injuries, but declined to describe their severity or exact nature.
“I can confirm that the male did have some obvious injuries,” Securo said, explaining that investigators were still working to determine how those injuries occurred.
Police also recovered several objects from the residence that could potentially have been used as weapons.
Among the items seized were blades that have since been submitted for forensic examination.
Investigators are attempting to determine whether any of those objects were connected to the man’s death.
A postmortem examination and other forensic testing are expected to play an important role in establishing the cause of death and reconstructing the events leading up to the discovery.
By Friday, detectives had confirmed that the two men were brothers who shared the property.
Authorities subsequently established that they were twins.
The revelation has added another heartbreaking dimension to the case, which police say has had a profound effect on the men’s family and friends.
“This sort of incident has a profound impact on the family, loved ones and friends of all those involved,” Securo told reporters.
She extended condolences to the grieving family and requested privacy as investigators continued their work.
Police have not publicly identified the victim, and authorities have not disclosed whether the brothers had a history of arguments or domestic disputes.
Investigators are also examining whether either man had previous contact with police or other government agencies.
On Saturday, October 10, authorities confirmed that Grillo had been formally charged with one count of murder.
He appeared before Northbridge Magistrates Court by telephone from Fiona Stanley Hospital, where he was receiving medical attention while remaining in police custody.
During the hearing, prosecutors revealed that there were significant concerns regarding Grillo’s mental health.
Police prosecutor Sergeant William Peacock told the court that Grillo had been restrained to his hospital bed because of concerns for the safety of medical staff.
Authorities were reportedly making arrangements to transfer him to a specialized forensic mental health facility.
The exact nature of his medical condition has not been publicly disclosed.
The concerns raised in court do not establish a motive for the alleged killing, and officials have not announced whether mental competency will become an issue in future proceedings.
Australian courts, like those in the United States, can consider a defendant’s mental fitness to participate in criminal proceedings when appropriate.
However, an assessment of mental fitness is separate from determining whether someone committed a crime.
Grillo has not entered a publicly reported plea, and the murder charge remains an allegation that prosecutors must prove in court.
He is expected to appear before a magistrate again on Friday, October 16.
Meanwhile, the investigation has shaken residents of Orelia, a residential community approximately 20 miles south of central Perth.
Neighbors said they were stunned to see police vehicles and forensic teams surrounding the property.
Ian Urquhart, who lives on Nye Way, told ABC News Australia that the neighborhood is generally peaceful and that he was shocked to learn someone had died at the house.
Another local resident, Vicki Gear, expressed sadness for the family and noted that many older people live in the surrounding area.
The heavy police presence continued into Friday as investigators searched for evidence inside and outside the residence.
Photographs from the scene showed police vehicles blocking access to the street while forensic officers carefully examined the property.
Investigators were seen searching the backyard, where the victim’s body had been recovered, and examining other areas that could provide clues about what happened.
Police have emphasized that there is no ongoing threat to the surrounding community.
Authorities believe the circumstances were confined to the residence and have not indicated that any additional suspects are being sought.
Still, several important questions remain unanswered.
Detectives have not revealed when the victim was last seen alive, how he died or what may have led to the alleged confrontation between the brothers.
Investigators have also not publicly established whether the victim’s body was deliberately concealed or whether the disturbed soil found in the yard is connected to the suspected killing.
Those questions will likely be addressed as forensic testing continues and police gather additional witness statements.
The case is being investigated as a suspected family violence homicide, a classification that can include deadly violence between relatives living in the same household.
Although domestic violence is frequently associated with intimate partners, it can also involve parents, children, siblings and other family members.
In this case, the alleged involvement of one twin brother in the death of the other has made the tragedy particularly difficult for the family and surrounding community.
For the relatives who alerted police, what began as a visit to check on loved ones has ended in a devastating loss and a murder investigation.
One brother is dead, while the other faces a serious criminal charge that could carry a lengthy prison sentence if he is convicted.
Western Australian authorities say their investigation remains active, with additional forensic examinations and interviews expected as detectives work to establish exactly what happened inside the home.
