A three-year-old boy who died earlier this week after being left in a car for three hours in extreme desert heat is seen smiling and happy in recently released photos taken before his tragic death.
Hayden Nelson died on Sunday afternoon after a family friend, Courtney Arnold, reportedly forgot the child in her car in the parking lot of Abundant Life Church in Phoenix, Arizona.
Arnold was at choir practice at the time with Nelson's
mother, Tiffani Nelson.
