Thais seek truth about killings

Thailand's so-called Red Shirts will take to the streets this weekend, almost a year after their failed attempt to bring down the government.

Close to 90 people died in those protests and the authorities' bloody offensive to stop the mass rallies.

As the government prepares for parliamentary elections, many of the victims' families are still searching for answers to what happened to their loved ones in last year's unrest.
