The retrial is underway in Douglas County for a man accused of strangling his wife so he could collect $300,000 in life insurance money.

The Lawrence Journal-World reports that 56-year-old Martin Miller is charged with first-degree murder in the July 2004 death of his 46-year-old wife, Mary Miller. His 2005 conviction was overturned last year.

Martin Miller’s former mistress, Carrie Parbs, testified Friday that Miller talked about divorcing his wife and marrying her. Parbs said Miller later backed out of the idea when he thought of how it would affect his finances, business, church and children.

Douglas County Coroner Erik Mitchell began testifying Friday about his finding that asphyxiation was the cause of death. The defense blames the death on natural causes. Mitchell’s testimony will continue Monday.
