According to the Faulkner County Coroner, heart disease contributed to Miles' death. It appeared the man's body had been in the lot for nearly a week.
Coroner Patrick Moore said it appears Miles lived in the Los Angeles area in California, but he may have recently been in Tennessee and was simply traveling through Arkansas.
So far, officials have not been able to contact next of kin to notify them of Miles' death.
