The Lady in the Long Dress: Arizona State Prison Complex

Reviewed by Josh N · Updated September 1, 2026 · How we verify

Arizona’s execution chamber sits behind the walls of the Arizona State Prison Complex at Florence, a hot, low-slung institution in the Sonoran Desert about an hour southeast of Phoenix. It is the oldest state prison in Arizona, the direct descendant of the territorial lockup at Yuma, and it is still very much in operation. The ghost stories attached to it, a woman in a long dress, shadow figures in Cellblock 6, cold spots in corridors that have no business being cold, are exactly that: stories. They come from staff and visitors rather than from any record, and no part of the complex is officially recognized as haunted.

The Florence Complex at a Glance

• Where: Florence, the county seat of Pinal County, Arizona, in the lower Sonoran Desert
• Origins: the Florence Territorial Prison, which received the inmates of Yuma Territorial Prison when Yuma closed in 1909
• Run by: the Arizona Department of Corrections
• Distinction: the former Arizona State Prison, and the location of Arizona’s execution chamber
• Access: an active prison. There are no public tours and no legitimate way inside
• What people report: apparitions, shadow figures, orbs, unexplained noises, sudden cold spots

The Prison That Inherited Yuma’s Inmates

The complex has a clean origin point. In 1909 the Yuma Territorial Prison, the one later memorialized by the movie 3:10 to Yuma, was closed and its inmates were relocated to the new Florence Territorial Prison. Arizona was still a territory; statehood was three years away. What arrived in Florence was not just a population of prisoners but a whole institutional culture, transplanted intact into a desert town that has never really stopped being a prison town since.

That transplant shaped Florence permanently. As of 2016 the town was home to multiple state, federal, county and private prisons, including the Florence complex, the neighboring Eyman complex, privately operated facilities, and county lockups for adults and juveniles. During World War II a large prisoner of war camp for German and Italian prisoners, Camp Florence, stood just north of town. A visitor driving in from State Route 79 passes fence line after fence line before reaching a Main Street preserved well enough to have served as a movie set.

The Hanging That Ended Hanging in Arizona

Most of the darkness people attach to Florence is real, and it is documented. In the 1930s Eva Dugan was convicted of murder and sentenced to be executed by hanging. The hanging went catastrophically wrong: it resulted in her decapitation, and the horror of it pushed the State of Arizona to abandon the rope and adopt the gas chamber as its method of execution. The Florence complex remains the site of Arizona’s execution chamber, which is the single fact that does more than any other to keep the ghost stories circulating.

Death row itself is no longer here. Condemned men are held at the Arizona State Prison Complex at Eyman, the adjacent facility also run by the Department of Corrections. Accounts that place former death row inmates wandering the Florence cellblocks tend to blur the two, which is worth keeping in mind when you hear them retold.

Winnie Ruth Judd and the Women Tried Across Town

The second Pinal County Courthouse, built in 1891, was where three of Arizona’s most notorious women faced trial: Pearl Hart, Eva Dugan, and Winnie Ruth Judd. Hart, an Old West outlaw who committed one of the last recorded stagecoach robberies in the United States, was tried in 1899 and acquitted, only for the judge to order a second trial that convicted her and sent her to prison for five years.

Judd’s case is the one that most often surfaces in Florence’s ghost lore. A Phoenix medical secretary, she was found guilty of first-degree murder on February 8, 1932, for the killing and dismembering of Agnes Anne LeRoi and Hedvig Samuelson. Her appeal failed. She was sentenced to be hanged February 17, 1933, and sent to the Arizona State Prison in Florence to wait. The sentence was overturned after a ten-day hearing found her mentally incompetent, and on April 24, 1933, she was moved to the Arizona State Asylum for the Insane instead. She was in Florence, under sentence of death, and then she was not: a story with the shape of a haunting even before anyone claims to have seen anything.

The Lady in the Long Dress and Cellblock 6

None of the following is verified, and none of it appears in any official record. It is repeated by staff, by former employees, and by people who have worked around the facility, and it is offered here as reported experience only.

• The Lady in the Long Dress. The best known figure in the prison’s folklore, described as a woman in period clothing and said in the retellings to be a former employee who died within the walls. No documentation supports the identification.
• Shadow figures in Cellblock 6. The block with the heaviest reputation. Reports describe dark shapes moving along the tier and unexplained points of light in photographs.
• Cold spots. Sudden drops in temperature in enclosed corridors, described in a building that spends much of the year fighting triple-digit desert heat.
• Unexplained noises. Voices, footsteps, and sounds attributed to men who died in custody.

As always at prisons, the ghosts get assigned the names the history already supplied. An institution that has held condemned prisoners since territorial days and still houses the state’s execution chamber does not need anything supernatural to feel oppressive, and most of what visitors describe can sit comfortably in that fact.

Getting Close to Florence Without Getting Inside

The Arizona State Prison Complex at Florence is a working maximum-security facility. It is not a museum, it does not run paranormal investigations, and there is no visitor experience beyond what the Department of Corrections permits for people with business there. Treat any invitation to tour the cellblocks with suspicion, and do not go looking for angles along the perimeter fences.

What you can do is see the town that grew up around the prison. Florence holds a National Historic District with more than 25 buildings on the National Register of Historic Places, and McFarland State Historic Park on Ruggles Avenue occupies the first Pinal County Courthouse, built in 1876, with displays covering the town’s history including the wartime camp era. The courthouse of 1891 where Hart, Dugan, and Judd were tried still stands as part of the same historic core. For anyone chasing the story behind the walls, that is where the accessible half of it lives. Go in winter if you can: summers here are brutal, and the monsoon storms that arrive in July, August, and September bring heavy downpours and flash flooding to the desert around the town.
