Police - Cold Case Information
Robert Trimborn – Case number 92-72814

On September 22, 1992, Robert Trimborn did not show up for work at Honeywell Bull in the City of Phoenix.  Robert was normally a very reliable employee and co-workers became worried when they could not contact him.  Glendale Police Officers went to Robert's home near the area of 61 Ave and Greenway Rd.  Officers entered the home and found Robert inside the victim of an obvious homicide. Friends of Robert reported they last saw him at a bar near 7th Ave and Camelback Rd in the City of Phoenix.  Some witnesses have referred to this location as a "gay" bar.  Robert was known to meet males at local bars and take them to his residence to have dinner. Evidence in the home suggests Robert did have a visitor for dinner on the night of his death.  Robert was a resident of the Phoenix Metro area for many years after moving here from the State of Minnesota, where his family still lives.  As of this time there is no known motive or suspect in the death of Robert.
