HOBART, Ind. (AP) -- An autopsy has found that a competitive billiards player from Michigan whose body was found in an Indiana pond died from asphyxiation.

The Lake County coroner's office also ruled 45-year-old Dawn Fital's death Saturday an apparent homicide.

An Ann Arbor, Mich.-area man accused of killing the Ypsilanti, Mich., woman was arraigned Saturday at the Washtenaw County jail.

Greg Noack is accused of killing Fital -- who had been his girlfriend -- and dumping her body in a pond behind a strip mall in Hobart, Ind.

The Times of Munster reports police think Fital was killed Monday in Michigan.

Two days after Noak's Tuesday arrest in Merrillville he led officers to her body. Divers found it inside a suitcase dumped in a pond behind a Toys R Us store.
