Brigette, handwriting like this does resemble the way many oldsters write, particularly those who have significant arthritis--the stiffening of the hand and fingers does not make it easy to write in the rounded, flowing style many of us learned in school. I guarantee it, from experience!

Note the heavy blobs at the beginning & ending of each letter. That's a sign of "pausing" - perhaps copying it from a list of addresses, and not familiar with the "characters". Possibly someone who is "foreign". The deliberate slowness indicated in the writing may be indicative of someone not well educated. Spacing is mechanical, but not well thought out...note that in several places the characters go out to the edge, and the letters start to squash together.

It may have been licked to seal and the stamp too...and that gives a sample of DNA in the saliva for cross matching when they arrest the perp.
