[Gene C]

Throughout the trial and up until his execution, Guiteau was housed at St. Elizabeths Hospital in the southeastern quadrant of Washington, D.C. (Wikipedia)

However, the next sentence in the article seems to contradict that.
" While in prison and awaiting execution, Guiteau wrote a defense of the assassination he had committed and an account of his own trial, which was published as The Truth and the Removal." (Wikipedia)

An article in Mental Floss indicates Guiteua didn't (did not) spend any time there at St. Elizabeth's. (outpatient only ?)

Forrestal was just a guess. Interesting case though.
