She doesn't have to have any degree to be a coroner. I know it takes a little effort but look up the statutes that pertain to it:
(55 ILCS 5/3-3001)(from Ch. 34, par. 3-3001)
Sec. 3-3001. Commission; training; duties performed by other county officer.
(a) Every coroner shall be commissioned by the Governor, but no commission shall issue except upon the certificate of the county clerk of the proper county of the due election or appointment of the coroner and that the coroner has filed his or her bond and taken the oath of office as provided in this Division.
(b)(1) Within 30 days of assuming office, a coroner
elected to that office for the first time shall apply for admission to the Illinois Law Enforcement Training Standards Board coroners training program. Completion of the training program shall be within 6 months of application. Any coroner may direct the chief deputy coroner or a deputy coroner, or both, to attend the training program, provided the coroner has completed the training program. Satisfactory completion of the program shall be evidenced by a certificate issued to the coroner by the Illinois Law Enforcement Training Standards Board. All coroners shall complete the training program at least once while serving as coroner.
(2) In developing the coroner training program, the
Illinois Law Enforcement Training Standards Board shall consult with the Illinois Coroners Association and the Illinois Necropsy Board.
(3) The Illinois Law Enforcement Training Standards
Board shall notify the proper county board of the failure by a coroner to successfully complete this training program.
(c) Every coroner shall attend at least 24 hours of accredited continuing education for coroners in each calendar year.
(d) In all counties that provide by resolution for the elimination of the office of coroner pursuant to a referendum, the resolution may also provide, as part of the same proposition, that the duties of the coroner be taken over by another county officer specified by the resolution and proposition.
