The tape was seized on Oct. 18, 2001, from Jane Mathisen's desk at her King George Road real estate office. Insp. Geoff Nelson testified that he took the cassette tape, found inside a folder labelled "Peter's recordings," from a file cabinet beside Jane Mathisen's desk.
Nelson told the jury he recognized the male voice on the tape as that of William, or Bill, Peloza.
Peloza testified earlier in the trial that he and Jane Mathisen had another telephone conversation just hours before her death. At that time he said she told him she had a tape that may contain phone conversations between the two of them and that she was going to her office to listen to it.
Jane Mathisen's husband, Peter Mathisen, has been charged with second-degree murder in connection to her death in their home at 59 William St. shortly after midnight on Oct. 12, 2001. She was 49.
