BUTTE, Mont. (AP) — Broadcaster, historian and author Pat Kearney was found dead at his home in Butte. He was 59.

Butte-Silver Bow Coroner Lee LaBreche confirmed Kearney’s death on Tuesday. LaBreche says it is suspected that Kearney died of natural causes but an autopsy was planned because he had been in good health and was an avid runner.

Kearney was a television and radio broadcaster for more than 30 years and did the play-by-play for Butte Central football for 23 of the past 25 years. He organized in the Butte Sports Hall of Fame in 1987 and was inducted in 2009.

Kearney had written several books about Butte and one about the Montana-Montana State football rivalry.

LaBreche says Kearney was just finishing a book about the Berkeley Pit.
