Gregory Hopkins, 66, had not posted the bond yet Tuesday and remained in the Beaver County Jail.
He was arrested in January and charged in the 1979 death of 23-year-old Catherine Walsh, and was supposed to go to trial last month.
He had been held without bond, but his attorney asked that bail be set when last month's trial was delayed indefinitely.
That happened because the DA appealed a judge's ruling that a pathologist's report was "too vague and imprecise" for the doctor to testify as a prosecution expert.
Hopkins has denied killing Walsh, but acknowledges a sexual relationship that ended before she died.
