Reports: Slain bookseller Sherry Black unknowingly bought stolen items from gang member with history of threats

SOUTH SALT LAKE — The fatal stabbing of bookseller Sherry Black was part of a particularly brutal attack, police said Wednesday as they continue to investigate her Nov. 30 death.

Authorities have completed an autopsy of Black, 64, the mother-in-law of Larry H. Miller Group CEO Greg Miller, said South Salt Lake police spokesman Gary Keller.

"She was physically beaten and stabbed more than once," Keller said. "Her wounds did cause a considerable amount of blood loss at the crime scene."

Black was killed in the shop she ran with her husband, B&W Billiards and Books, 3466 S. 700 East. Keller said police still have no motive and no suspects.

The Deseret News has learned about a transaction in which Black purchased rare, stolen LDS books from a Juggalo gang member with a history of making threats. The incident occurred in February of 2009.

Lorin Nielsen, 20, was arrested and charged with stealing books from the Bluffdale home of his father, who is a polygamous church president. Nielsen pleaded guilty in April 2009 to theft, a third-degree felony, and theft by deception, a second-degree felony. He was sentenced to 90 days in jail.

Nielsen was booked into Salt Lake County Jail on Monday for a violation of his probation in the theft case. Detectives, however, would not say whether he is being investigated in connection with the homicide.

In March 2009, Nielsen's father told detectives he had noticed some rare LDS books missing from his home library, according to police reports. He reviewed security camera footage and saw his son removing the books on Feb. 20, when he had been at the home for a funeral. The home also functions as a church meeting place.

When the father showed the video to his son, Nielsen admitted taking the books and said he sold them at Black's B&W Billiards and Books store, police reports state. Nielsen warned his father "if he got police involved he will set off a chain of events he's not going to like because he is a member of a gang," the report states.

Police say the son was affiliated with an Insane Clown Posse, or Juggalos gang. The father was afraid of his son because of the gang association and his history of carrying weapons, the reports state.

The father's wife told detectives a man doing construction work at the house had seen Nielsen and his half-brother in and around the library. When the family searched Lorin Nielsen's car, he became upset and "threatened serious harm" to his father and the family, police reports said.
