Gunman went on a rampage in a small Mississippi town on Friday, killing his ex-wife and five other people in three locations before sheriff's deputies arrested him, the county sheriff and witnesses said.

Iran PressAmerica: A lone gunman killed six people including his ex-wife and stepfather Friday at multiple locations in a tiny rural community in northern Mississippi, the sheriff said, leaving investigators searching for clues to what motivated the shocking rampage.

The bloodshed occurred in Arkabutla, a rural hamlet of less than 300 people in Tate County in northern Mississippi, about 40 miles (60 km) south of Memphis, Tennessee.

The gunman was identified as Richard Dale Crum, 51, and was charged with first-degree murder, Tate County Sheriff Brad Lance told reporters.

Armed with a shotgun and two handguns, 52-year-old Richard Dale Crum opened fire at about 11 a.m. and killed a man in the driver’s seat of a pickup truck parked outside a convenience store in Arkabutla, near the Tennessee state line, Tate County Sheriff Brad Lance said. 219
