“The condition of the remains of Sister Wilhelmina Lancaster has understandably generated widespread interest and raised important questions. At the same time, it is important to protect the integrity of the mortal remains of Sister Wilhelmina to allow for a thorough investigation,” Johnston said in his statement.
“I invite all the faithful to continue praying during this time of investigation for God’s will in the lives of the Benedictines of Mary, Queen of Apostles; for all women religious; and all the baptized in our common vocation to holiness, with hope and trust in the Lord.”

According to the sisters, at some point after the burial Sister Wilhelmina’s coffin sustained a crack down the middle that let in moisture and dirt. Her body was discovered to be covered in what the sisters described as a layer of mold after being exhumed.
CNA asked Hess and another expert about the possibility that the body might have been preserved through a chemical process called “grave wax.”

“Grave wax” is an uncommonly seen but natural phenomenon that encases a corpse or parts of a body in a shell of soap-like fatty tissue, called adipocere, which slows or stops the normal decomposition process, which can preserve the human remains for many years — even centuries.
Two so-called “soap mummies” — dubbed “Soap Lady” and “Soap Man” — were exhumed in 1875 during digging for the foundation of a train depot in downtown Philadelphia decades after they died.
“This unusual preservation occurred because water seeped into the casket and brought alkaline soil with it, turning the fats in his body to soap through a type of hydrolysis known as saponification,” according to the Smithsonian Institution, which has kept the man’s remains in climate-controlled storage in the Smithsonian’s Museum of Natural History in Washington, D.C. The woman’s remains are on exhibit in Philadelphia’s Mütter Museum.
Hess said that grave wax typically only materializes in different parts of the body, but he said it could cover the entire body. He added that grave wax will break down over time.
Hess said that he “highly” doubts that grave wax could have preserved Sister Wilhelmina’s body to appear the way it currently does and without any foul odor, “unless she was in a highly alkaline environment.”
Mortician Barry Lease, president and CEO of the Pittsburgh Institute of Mortuary Science, told CNA that a soil analysis testing the pH, or point hydrogen, of the environment, would reveal whether Sister Wilhelmina’s former burial grounds are highly alkaline. According to the Mütter Museum, “Adipocere formation is not common, but it may form in alkaline, warm, airless environments, such as the one in which the Soap Lady was buried.”
Lease said that it’s difficult to project where the body would be in the decomposition process if it was covered in adipocere but added that the body’s decomposition “should be further than that,” referring to a photo of the body taken by CNA on May 20.
“You shouldn’t be recognizing her with just a little bit of mold on her face,” Lease said.
“An unembalmed body in the ground for four years should have some odor coming off of it that would be noticeable,” he added.
“If you’re telling me that this woman went into the ground unembalmed in a wooden box with no outer container in the ground and it was not sub-zero up in Alaska, I’m telling you, I’m going to start a devotion to this sister, because something special is going on there,” Lease, a practicing Catholic, told CNA.
