WHEATON, Ill. (AP) — Ohio authorities relying on DNA and public genealogy databases have arrested a man in connection with the 2016 deaths in Illinois of an elderly woman and her son.

The DeKalb County Sheriff’s Office announced Tuesday that 51-year-old Jonathan Hurst was arrested in Cincinnati, Ohio on Monday.

Extradition proceedings have begun to return the man to Illinois to face two counts of first-degree murder. Hurst, who formerly lived in Chicago, is accused of beating to death 85-year-old Patricia Wilson and her son, 64-year-old Robert Wilson, in their Sycamore, Illinois home in August 2016.
