Lancaster County, Pa., July 25, 2008
Michael Roseboro, a funeral director and father of four, claims he found his wife, Jan, drowned in the family swimming pool.
But after an autopsy shows she was beaten and strangled, police get a tip that Michael has been carrying on an affair with a woman named Angela Funk.
They bring the mistress in for questioning and ask about her contact with Michael on July 22, 2008 - the day of Jan's death.
Though the affair provided a motive, it was DNA evidence tying Michael to the crime that ultimately sealed his fate. He was convicted of murdering his wife, Jan, and sentenced to life in prison. Investigators do not believe Angela Funk had anything to do with the crime.
