Under a pseudonym, photographer Seph Lawless is known for his dark and foreboding pictures of abandoned buildings.
The images he captures have an eerie, surreal quality.
In support of his new photo book, "13: Hauntingly Beautiful," Lawless has provided us with photos of 13 real-life haunted houses across America.
Some are actual murder sites and others are places where corpses have been dumped. All are intensely creepy.
We begin our tour with the Haught Mansion in Brush Park, Michigan, which was an upscale brothel in its 1940s heyday.
Years after it closed, a number of dead bodies were found in the basement. The torsos and chests of the victims were marked with perfectly round circles.
This broken down palace in Michigan will make a cameo as Bruce Wayne's house in 2016's "Batman v Superman: Dawn of Justice."
A film assistant came across it while looking at Lawless' photos.
Detroit is full of ghost stories, especially on Temple Street. In 1942, three priests are said to have been murdered in this dilapidated Victorian mansion.
Neighbors from across the street say they'd heard ghosts stirring in the house, which was recently demolished to make way for new developments.
This abandoned home in East Cleveland was marked by ABC news as the dumping ground of a serial killer in 2013.
Three female victims were found in the house. The killer had put one of the women in the fetal position and wrapped her in plastic bags.
A man named Benjamin Albright accidentally shot and killed his son in 1958 in this Nova, Ohio, house. He later killed himself and his wife.
Called the Nova House, the home has been abandoned ever since. Some of the family's belongings are still inside.
It's suspected that this Milan, Ohio, house is where local witches practice their craft.
The original owner, known as the Milan Witch, is rumored to be buried underneath the front porch.
In Buffalo, New York, a local sheriff, Donald Caters, shot himself after his home went into foreclosure.
The house has sat vacant since the 1968 suicide. Locals claim they hear voices around the property.
Lawless believes slaves were kept in this Mississippi plantation house. Some of the walls have markings similar to what a prisoner might scrawl to pass time.
Lawless says this house was "emotionally draining to photograph."
This Texarkana, Arkansas, house sits in front of the road where the "Phantom Killer" took his victims. His crimes are often called the Moonlight Killings.
The Phantom Killer was never caught — but some speculate that his crimes are actually the early work of the Zodiac Killer.
The haunted Bailey Mansion is the real-life inspiration for the house in the first season of FX's "American Horror Story."
The show was set in Los Angeles but the actual location of the Bailey House (often referred to as "the murder house") is in Hartford, Connecticut.
Lawless shot this 1892-built house in downtown McKeesport, Pennsylvania, the day before it collapsed from a fire.
"It's truly frightening and it still gives me chills thinking about it," says Lawless.
