Actress Aasha Davis, best known for her roles on popular television shows like "Grey's Anatomy" and "Friday Night Lights" faced her toughest role yet, when she went on television a year ago to ask the public for help in finding her missing sister, Leslie Ann Herring. Now a year has passed and her sister's body has still not been found, but police think they've caught the woman's killer: her husband, Davis's brother-in-law, Lyle Herring, Sr., who was arrested Wednesday.

According to police reports, Herring had a heated argument with his wife on February 8, 2009. Aasha reported her "creature of habit," 46-year-old sister missing shortly thereafter, when she did not report to work after a few days.

When police investigators questioned Herring about his wife's disappearance, he was not cooperative, making him an instant suspect. Investigators described the man as being "fragmented, less than helpful and not behaving as a grieving husband."

During a press conference last year, Herring, a university recruiter, denied any involvement in his wife's disappearance. He appealed for his wife to come home. "Please give us a call," Herring said. "Let us know what's going on. We have a lot to talk to about." Police were not buying his act.

Herring will be arraigned today in Los Angeles. He faces up to 15 years in prison if convicted.
