Luis Ramirez, 70, was found slumped over in his silver Chrysler minivan just before mid-day on Sunday.

Emergency personnel responded and found the man dead. It appeared he'd been dead for quite a while before he was found, according to police.

A medical examiner determined Ramirez had died of natural causes.  Ramirez had been dead for up to two days before his body was discovered.
