Gunmen shot dead a former Miss Venezuela and her British-born partner in front of their five-year-old daughter, who was wounded in an attack that dismayed the crime-plagued nation, authorities said Tuesday. Monica Spear, a 29-year-old soap opera star, and Thomas Henry Berry, 39, were killed in what appears to have been a botched robbery after their car broke down on a highway in northwestern Venezuela late Monday, police and prosecutors said.
