7 disturbing Spokane spots to avoid this Halloween

Built around 1898, the lavish house of mining baron Patsy Clark is one of few Spokane haunted landmarks where a sitting president has dined. George Bush enjoyed a meal during the mansion's restaurant period in 1989. Over the years, some staff claimed to have felt the presence of Clark's long-deceased wife Mary, especially in the basement wine cellar. The mansion is now home to the law firm of Eymann, Allison, Hunter, Jones, P.S. and is available for weddings and events.

Though the plaque on the wall now reads "Pearl Apartments," in 1998 they were known as the Helen Apartments and were managed by a serial killer named Stanley Pietzrak. Tenants claimed he converted the walk-in freezer to a torture chamber. After one of his residents disappeared, police received a tip to check the basement where they found bone fragments in the furnace. Though Pietrzak was only convicted of one murder, between 1976 and 1998, at least four women died suspiciously or disappeared altogether while in his company.

In 1858, Colonel George Wright began a campaign of violence and revenge against the Pacific Northwest's Indian tribes after two prospectors were murdered. In an effort to deprive the local tribes of their livelihood, Wright ordered his men to massacre between 700-900 horses near the Liberty Lake. The first picture shows the site in 1920.

After the horse slaughter incident, Colonel George Wright sent word to local tribes that he was ready to negotiate peace in September of 1858. The Yakima chieftain Qualchan, who had developed a brutal reputation for guerilla warfare, received the message and arrived in camp. Wright recorded what happened next: "Qualchan came to see me at 9 o'clock, at 9:15 he was hung." Hangman Valley gets its name from this incident. The spot where he was executed is about 20 minutes south of Spokane. Despite the fact that Qualchan vehemently fought against the encroachment of whites into native territories, today a local golf course bears his name.

When headstones become broken or unsightly, they are discarded in the cemetery's Bone Yard. One of Spokane's most scenic borders on Indian Canyon Park near Greenwood Memorial Terrace. Some residents have decided to use this spot as a designated drinking area so if you do stumble upon it, make sure to clean up after yourself.

Possibly the region's most infamous haunted house, Monaghan Hall has been accused of a laundry list of paranormal occurrences. This includes organ music playing by itself, unnatural growling, and furniture moving on its own. There was even an alleged exorcism of the mansion in 1975. Some say the house is haunted by the original owner's son, John R. Monaghan, who was killed by rebel Samoans in 1899 and is immortalized on a statue in front of the Spokane Club. Monaghan Hall currently serves as Gonzaga's music conservatory.

Rudolph Hahn was a strange, Great Gatsby-like character who liked to race cars, throw lavish parties, and provide electro-shock therapy and other illegal procedures out of his basement. Hahn purchased the residence on Spokane's South Hill in 1924 and spent the majority of his time there with his on-again, off-again wife Sylvia. In 1940, his wife was found dead of an apparent suicide, though police initially suspected Hahn. Five years later he was fined $1,000 after one of his patients died mid-operation. Hahn moved into a penthouse apartment in what is now the New Madison where his odd life was cut short after a hearing-aid salesman stabbed him in the heart with a French WW1 Bayonet from his own weapons collection.
