BISMARCK, N.D. (AP) — North Dakota’s Board of Chiropractic Examiners has revoked the license of Chad Isaak, the man convicted of killing four people at a property management company in Mandan.

The seven-member board voted unanimously recently to revoke Isaak’s state chiropractic license which had been suspended pending the outcome of his murder trial, the Bismarck Tribune reported.

In August, a Morton County jury convicted Isaak in the April 2019 slayings of RJR Maintenance and Management co-owner Robert Fakler, 52; employees Adam Fuehrer, 42; Bill Cobb, 50; and his wife, Lois Cobb, 45.

Isaak lived in Washburn on property owned by RJR, but no definitive motive was established for the crime. All four victims were shot and stabbed.

Isaak faces life in prison when he is sentenced Dec. 28.
