We’ve been on the ground in Syria, as the fall of dictator Bashar Al Assad brings an end to his family’s 54 years of authoritarian rule. We ventured inside Sednaya Prison, a place known as "the Human Slaughterhouse" due to the horrific torture and murder that took place there. Enemies of the regime were sent to Sednaya and often never heard from again. It’s estimated that 30,000 people were killed in the prison since the start of the Syrian civil war in 2011. This dispatch is a look inside Sednaya Prison and the aftermath, as Syrians try desperately to search for their missing loved ones.
