In his book, Kennedy wrote that the mysterious “John Doe No. 2” turned out to be “someone’s memory playing tricks on him.” FBI sketches of “John Doe No. 2” were released worldwide after witnesses said that man was with McVeigh when the bomb truck was rented in Junction City, Kan.
Kennedy said he is certain there are no others involved in the bombing because McVeigh and Nichols used a telephone calling card purchased under a fake name in their plot to find bombing materials and to keep in contact. The FBI was able to track where the two called.
“If there in fact was another conspirator, I am absolutely convinced that we would have been able to identify him through the telephone (records) and through other investigation that we did which was exhaustive,” he said.

Pretty unlikely for more than one person to have the exact same memory failure - good enough for a police sketch artist.
If I recall, John Doe #2 would have to be playing tricks with several different peoples’ memories at different times.
Wasn’t he with them at a diner and also with them answering the door at a hotel room?
turned out to be someones memory playing tricks on him.
