There are probably quite a few potential matches for white males between the ages of 55 and 65 with a height of 5'10" OR 6'6". Add a hair color that could be blonde OR grey (which could have been any color 20 years ago then) and undetermined eye color - and the possibilities are daunting.
I am including Michael Clarke here because he has a tattoo on an unknown arm and strangely enough, has heights listed on similar extremes as this UID.
His family apparently lost saw him in 1987, but he has a booking record from 1990. I found a booking record for a Michael Tyler Clarke from June 1990 in Polk, FL. Not sure if it is the same person, but the height listed is 5'9". NamUs has potential height as 6' to 7'. Pretty big spread, like with the UID!
Mr. Clarke's hair is listed as red/auburn whereas NamUs has the UID's hair as grey and the Coroner's Office has it listed as blonde. If the UID's hair was grey, then this doesn't rule out Mr. Clarke.
His eye color is listed as blue, but the UID's eye color is unknown due to clouding.
Age-wise, it looks like Mr. Clarke would have been 65 in 2012 which is the high end of the estimated age range. The UID gave his age as 58 in the 2008 interview with the
San Francisco Chronicle. If that is his true age, he would be around 62 in 2012.
Finally, Mr. Clarke has no fingerprints, DNA, or dentals listed available for comparison so he likely has not been compared yet.
