Mexico remembers its dead amid drug wars

People across Mexico are marking the Day of the Dead, a time to remember deceased family members. One woman, Katiushka Rodriguez, lost two family members in an incident which saw 18 men killed when a drug gang mistook them for rival gang members. The men were kidnapped, killed, and then buried in a mass grave, which was discovered a year ago. Rodriguez has taken it upon herself to see that justice is done. A year ago she met with Felipe Calderon, the president of Mexico, who promised to investigate the killings. Franc Contreras reports from Morelia.
