ABC News reported that Keach, known for his role as Mike Hammer on television and for his work onstage, has died at 85. The ABC News summary available to this desk did not list an author for the report.

The Guardian, carrying an Associated Press report, said the actor died in Poland on Tuesday. Citing his wife, the report said Keach died "after a long and difficult battle with a serious heart condition and heart failure." According to The Guardian, Keach was best known for playing the scruffy private eye Mike Hammer on television, and his career was nearly derailed after he was imprisoned in 1984 for trying to smuggle cocaine into Britain. The summary available to this desk ends before the report is complete.

The New York Times reported that Keach, an actor who embodied Hamlet and Mike Hammer, died at 85. Its summary said he missed out on several major film roles but found steady work in the theater, on television and in movies. The article was written by Barry Singer.

The three reports agree on Keach's age and his association with Mike Hammer, but they differ in emphasis. The New York Times summary focused on his career across theater, television and film, while The Guardian focused on his health and his 1984 arrest. Only The Guardian, through its Associated Press-sourced report, attributed a cause of death, and it did so as stated by his wife. None of the three summaries available to this desk gave details of services or arrangements.
