Sister's murder drives NBC's Hall

PASADENA, Calif. (AP) — NBC's Tamron Hall says her work on the series "Deadline Crime" is partly motivated by the feeling that she failed her sister, who was murdered in 2004.

Hall's crime series begins its second season on the Investigation Discovery network this spring. Hall hasn't talked about her own family's story as part of the series but opened up about her regrets Thursday at a news conference.

Hall said she could see her sister was a victim of domestic violence, but she didn't know what to say.

Hall says having gone through something similar has helped her interview people who have lost loved ones to crime.
