MERRILLVILLE, Ind. (AP): A prison inmate has been charged with murder after investigators say he bragged to an acquaintance about killing two people in 2008. Kenneth Sandidge was serving a four-year term on an unrelated firearms violation in the state prison at Westville when he was charged recently by Lake County prosecutors. Investigators believe the man fatally shot two people inside a Merrillville apartment about six years ago.
