The children and a lady were shot to death, according to the police, who subsequently received a call at around 9.20 am. Whether Marcus was in that man’s place is unknown.
About ten minutes later, the police arrived on the scene to discover all five members of the family dead from gunshot wounds in the garage and on the first and second floors of the suburban cul-de-sac home.
Next to Marcus’ body inside the garage, investigators discovered a firearm.
Three years, one week, and one day have passed since Marcus and Tara’s youngest son, Conor, passed away from paediatric cancer.
She shared a photo of her holding him on Facebook on September 3, writing: ‘Somehow it’s been three whole years since we had to say goodbye to Conor.
‘What wouldn’t I give for another perfect moment like this one, even if just for a heartbeat.’
It is still unknown whether Marcus’ alleged murder-suicide of his family and the anniversary of their son’s passing are connected.
The deaths of the family are still being looked into.
