AMC's head of original programming Joel Stillerman announced that fans of The Killing will find out who killed Rosie Larsen in season two, acknowledging the season one cliffhanger disappointed a lot of people.

"For everybody who was frustrated, we hear you," said Joel Stillerman, addressing reporters at the semi-annual Television Critics Association press tour. RELATED: Andrew Lincoln Teases Spring Start Date for The Walking Dead Rick Grimes Movie

"We would have taken a different approach to managing the expectations about what was going to happen," said Joel Stillerman. "It was never intentionally meant to mislead anybody. Our goal was to create a brilliant piece of character-based story telling and to try to do something [different]. We think we got there but we definitely didn't manage expectations the way they should have been managed."

"I can say definitively," added Joel Stillerman. "You will find out who killed Rosie Larsen in season two."

Joel Stillerman also addressed the status of The Walking Dead, which earlier this week saw showrunner Frank Darabont step down to be replaced by writer and executive producer Glen Mazzara.

"I can report that production is not go to miss a beat and we're going to make our air date," said Stillerman. "What I've seen [so far] and what I've seen coming down the pike, we're going to take what we started last year and really move it to the next level. It's going to be an incredible season."

The Walking Dead is scheduled to premiere its second season Oct. 16.
