David Louden, 39, and his son Harrison were discovered dead at their home in Kidderminster, Worcestershire, on Friday. Heartfelt tributes to David, who was a serving West Mercia Police officer, and Harrison have been left outside their home.
Police are now treating the deaths as a murder-suicide.
Damian Barratt, Assistant Chief Constable, said: “West Mercia Police are now treating the death of Harrison as a suspected murder and the death of David as a suspected suicide.
“David Louden and his three year-old son, Harrison, were tragically found dead at their home in Kidderminster on Friday 13 August 2021. At the time the deaths were treated as unexplained and investigation was launched into the circumstances.
“Post-mortem examinations have now taken place and the investigation team, in conjunction with the coroner, are satisfied no other parties were involved.
“However, safeguarding reviews are now underway and there will be an inquest to provide an official determination, so we are unable to comment any further at this time in relation to the circumstances or the investigation.
“This is a dreadfully sad case and our thoughts are with David and Harrison’s family and friends. They have requested that they be allowed to grieve.”
Police and paramedics arrived at the home at 9.21am, after being called to reports of concern about the family’s welfare.
David’s wife Samantha led a tribute to her husband and son, along with their wider family.
In a statement, she joined other family members in expressing their “deep shock, grief and devastation at the loss of two much loved family members.”
They said: “David was a kind, loving, considerate, amazing father, husband, son, brother, uncle, friend and colleague.
“Harrison was a happy, well-loved little boy. They will both be forever missed and loved.”
Several bouquets of flowers were laid at the scene along with a soft plus elephant toy with the message “Rest in peace, sleep well. In our thoughts and prayers.”
Another message read: “To family and friends. So sorry for your loss – we’re all thinking of you.
“My heart goes out to you all, it’s such a tragedy. Both lives gone too soon.”
