A Mum and Dad were found dead beside their car - with their three young sons still strapped into the back seats.


Thankfully, the boys - aged between just 8 months and four years - were discovered unharmed. 


Police in Florida are now investigating the mystery, which happened on New Year's Eve.


Early on Saturday morning, Police were called to the scene when their car was spotted with the hazard lights flashing.


When Police arrived at 2.08am, Daniel (32) and Heather Kelsey (30) were found unconscious, and later pronounced dead.


Speaking to the News Journal, a friend of Daniel’s, Jerrell Jackson said their deaths were “unbelievable”.


"I can tell you Dan was a loving, devoted father (who) did anything for his kids.”


"I loved Dan like a brother ... every time you saw him, you saw his kids.


Although their deaths are not being treated as suspicious, the pair will be required to undergo a post-mortem examination to determine the cause of death.


A spokesman for the Volusia County Sheriff, Andrew Gant, said there were no signs of foul play, the Daily Mail has reported.
