A television journalist walking with his grandson in a city street in east Guatemala was shot dead on Tuesday, a colleague on his cable network told AFP. Victor Valdez, a 65-year-old Guatemalan journalist who led a cultural program on the Guatevision network for the past 29 years, was gunned down while walking with his teenaged relative in Chiquimula, a city near the border with Honduras where he lived. Edwin Paxtor, a journalist for Guatevision and the Guatemalan newspaper Prensa Libre, said the motive for the deadly attack was not immediately known.
