A brother and sister have died after their dad left in his truck for five hours in 32C heat.
Ryan Dennis, 3, and his older sister Teagan, 4, were found in the footwell of Dustin Lee Dennis’ vehicle after he went for a nap.
They were found on Saturday in Tulsa, Oklahoma, after he returned home after driving them to a QuikTrip convenience store in the midday sun.
At 5.30pm Tulsa police received a call after Dennis said he couldn’t find his children.
He said he took a nap after returning from the store and when he woke, found the children on the floor his truck before moving them into the living room.
The 31-year-old was arrested at the scene and charged with two counts of second-degree murder, according to the arrest report.
It added: “The children had not been checked on for nearly five hours during the time they were locked inside the vehicle.”
They had no previous medical conditions but the exact cause of death has not yet been released.
Their bodies were identified by a family member the next day.
Tulsa PD are looking into video taken by a neighbour that shows Dennis leaving the truck and locking the doors without getting the children out.
He did not have full custody of the children.
On his Facebook profile he wrote the Thursday before they died: “Two in the morning up watching my kids sleep, I can’t believe they’re mine, I love them so much and nobody in this world could ever make me feel as loved as they do.
“The other day I was so depressed because I just missed them, and I got to thinking of when they get older and become adults.
“I hope our bond only grows stronger, I hope they always want to call me or see me just to talk or ask for advice. I can’t imagine this world without them,” he added.
Children can suffer symptoms of heatstroke within minutes of being trapped in a hot car as the temperature inside rises rapidly.
The inside of a vehicle acts like a greenhouse trapping in heat causing the temperature inside to rise very quickly.
Dennis is currently being held in Tulsa County jail on a $750,000 bond.
