Ronald was described as a 5-foot-10 white male weighing 170 pounds, with blond hair and blue eyes. He may have a mustache.

The Iowa Department of Public Safety’s Missing Person Information Clearinghouse lists his status as an involuntary disappearance.

    Suicide or faking death

    Excellent finding Sue. It is worth to check. The Police can check the missing report for his last wearing clothes description to match those of 2UMIA. However, it seems police treated this unknown white male as a drifter – “The individual may have been traveling from Ohio to California. He had a one dollar bill, pink blanket and a match book in his possession.”

    Does the DOE Network automatically cross reference the Iowa Missing Persons and Cold Case databases and vice versa? I saw one DOE case where they list who it is not ( Not Jodi Huesintraut (sp.?) specifically), but do they all do that? Case 2UMIA seems to fit this one..

    Sounds suicide to me.
