IN BRIEF : N.M. Athletic Heads Plead Innocent

<i> From Times wire services </i>

Former University of New Mexico Athletic Director John Koenig and two former associate athletic directors pleaded innocent today to charges in a 58-count indictment returned last month by a Bernalillo County grand jury.

Koenig, 45, was named in 47 counts of the indictment that primarily consisted of charges of making false public vouchers, fraud, criminal solicitation and conspiracy. Mike Dill, 45, was named in 11 counts and Terry Hearne, 43, in eight counts.

Koenig, who lives in Cape Girardeau, Mo., was forced to resign as athletic director on July 22, 1988, amid allegations that he had double-billed the school for travel and business expenses. The indictment against him was returned by the grand jury last March 16. Assistant Dist. Atty. Kathy Carter said the amount of money allegedly misappropriated is believed to be about $25,000. Dill resigned his position at the university in December, and Hearne was placed on administrative leave with pay pending the outcome of his case.
