WASHINGTON – A 56-year-old Mechanicsville, Maryland woman was arrested and faces charges for allegedly contaminating her roommate’s milk with human skin.

Sarah Preston Schrock is charged with felony contaminating/poisoning food/drink, three counts of second-degree assault and violation of a peace order.
According to the St. Mary’s County Sheriff’s Office, a roommate of Schrock said that, after being gone all day, she and two others poured milk from the home’s refrigerator to have during dinner. After one of the victims drank some milk, she began to choke on something that was in the drink. Deputies said she coughed up the substance, and discovered what appeared to be human skin.
Another victim drank the milk, and also felt something in the liquid, but gagged and coughed it up. The third victim poured out the milk.
The three then poured the rest of the milk into a strainer, and found what looked like human skin shavings in the milk container, according to the sheriff’s office.
On May 6, Schrock’s roommate went to the sheriff’s office and told investigators about what had happened, and alleged that Schrock shaves the bottoms of her feet and keeps the skin in trays in her bedroom.
Schrock was arrested and taken to the St. Mary’s County Detention Center.
