Is Wyoming Territorial Prison haunted?

The record — long form
Wyoming Territorial Prison is where Butch Cassidy did his time. The stone penitentiary went up in 1872 for the territory's 'evil doers of all classes and kinds' — one of the few federal prisons in the West, the only one in Wyoming, holding the railroad-town desperadoes the 'Hell on Wheels' settlements produced. Cassidy was prisoner there 1894–96 for horse theft, eighteen months of the Wyoming that made him, before the Wild Bunch and the legend.
The prison's population was the frontier's overflow — violent and desperate men in the stone block on the Big Laramie, the discipline on the second floor where the mess hall was. Only two of the thousand inmates died inside: the leper and Julius Greenwald, the Polish cigar maker who was prisoner No. 338 and whose cigars had a regional market. Greenwald died of natural causes; the staff says he's the ghost anyway — the cigar smoke that appears in the cellblocks, the footsteps and whistling and the female laugh in the empty rooms.
The prison became the university's stock farm for ninety years — cattle in the exercise yard, the experiment station in the buildings — until the '90s restoration made it a state historic site. The file keeps the prison's unusual mercy: a territorial penitentiary where the death toll was two, the famous inmate went on to the legend, and the cigar maker who died of a heart attack is the ghost the staff can't quite explain.
Wyoming Territorial Prison is the archive's Cassidy file — the 1872 penitentiary that held Butch Cassidy, the university stock farm for ninety years, haunted by the cigar-making prisoner who died of natural causes.
Why this file matters
Wyoming Territorial Prison is the archive's merciful-prison file — the territorial penitentiary that held Cassidy and a thousand others, lost only two inmates to death, and keeps the cigar-smoke ghost of the one who died of a heart attack.
A prison that became a farm keeps its ghost — the file's suggestion being that the Territorial Prison's hold is Greenwald's cigar: the smoke in the empty cellblock, the prisoner's trademark still detectable, and the building that was a stock farm longer than it was a prison.
