Two children are found dead after being 'locked inside their father's truck while he slept indoors' as temperatures soared past 90F

An Oklahoma man has been arrested after his two young children died after being locked inside his truck for five hours in 90 degree heat while he took a nap indoors.

Dustin Lee Dennis, 31, now faces two counts of second-degree murder after his kids, Teagan, 4, and Ryan, 3, were found dead.  

Police say Dennis told them he took a drive to a QuikTrip convenience store at around noon before returning to his Tulsa home and falling asleep for between four and five hours.   

After waking, Dennis told police that he was unable to find his children, according to Fox 23. 

Dennis allegedly claims he found the pair on the floorboard of the truck.

He called 911 and moved the children into the living room of the family home where paramedics pronounced the children dead.

Writing on his Facebook profile on Thursday, Dennis appeared to write about the love he held for his children, who did not live with him, online

Writing on his Facebook profile on Thursday, Dennis appeared to tell of his love for his children, who did not live with him.  

'2 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,' he wrote.

'If you don’t have kids you may not understand this but that is the scariest but most amazing thing to think of, watching them become their own person and seeing what they will experience and achieve. 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 continued.
