Two central Iowa men died yesterday in an apparent murder/suicide. Officials won’t say who shot whom, but the dead men have been identified as 60-year-old Ronnie Markham of Boxholm and 26-year-old Cory Jones of Ogden. The bodies were found in one of the men’s homes, north of Boxholm, which is a tiny Boone County town of 300 residents. Investigators say the men died of wounds from a 22-caliber handgun. Police were called to the residence at about 10 o’clock yesterday morning.
