Mamie Ethel Crowell, age 20, died in mid-April, 1930, in the office of Dr. Hans Arthur Paulsen, from an abortion performed on her that day. Two days later, Paulsen was booked for manslaughter by abortion. The father of the baby, Uriah Denniston, was booked as accessory. Paulson was held by the Coroner for murder by abortion. Denniston wasn't mentioned in the verdict. In early September, the indictment was quashed. The source notes "Circumstances suggesting judicial corruption."

Paulsen was born in Chicago in 1886, and died at Chicago's Martha Washington Hospital in 1944 at the age of 57 of a heart ailment. He was a graduate of the Chicago College of Medicine and Surgery, and first licensed to practice medicine in 1912..
