Television actress Aasha Davis has tried everything she can to find her sister, who has been missing for nearly seven weeks from her Hollywood home.
On Tuesday, the actress, who has had recurring roles on NBC's "Friday Night Lights" and The N's "South of Nowhere," joined police at a press conference to enlist the public's help in finding 45-year-old Lesley Herring.
"The days would start and I'd feel renewed and think we're going to figure this out, this will lead to information," she told ABCNews.com. "As night would creep in, I would get so sad and feel another day has passed without Lesley."
Herring has not been seen since Feb. 8. Though her husband, Lyle Herring, was the last to see her, it was Davis, 35, who called police two days later and reported her missing when she failed to show up at her job in the payroll department of a company in Glendale, Calif., that manufactures sprinkler alarm systems.
"Lesley Herring is missing under very suspicious circumstances," Detective Wendi Berndt, supervisor of the Hollywood detectives homicide unit, told ABCNews.com. "At this point we are thinking the worst."
Police say Lyle Herring is not considered a suspect but that he has been less than forthcoming.
Herring's family also said he has been evasive with them and said that he disappeared for two weeks around the time his wife vanished. He later turned up with his long dreadlocks cut off, with a wild story of how he had gone to Mexico to look for his wife because they were planning a vacation there and ran into some sort of gang who cut off his hair because he owed them money, according to Davis's husband Jesse Pforzheimer.
"I would describe his cooperation as fragmented and less than helpful, not someone I would expect as a grieving husband," Det. Chris Gable said at Tuesday's news conference, taking a surprisingly confrontational tack with Lyle Herring, who was standing nearby.
"We felt he could not come there and present himself as a caring husband asking for the public's help when he's not been very helpful to us in trying to find Lesley," Berndt said about Gable's surprise statement. But she added that police continue to look for other leads in Herring's disappearance.
"You have to question why he is reacting the way he is in this investigation. But we definitely put it out there that we are exhausting all clues we have in order not to do a rush to judgment or limit ourselves just to him," she said.
Lyle Herring made a brief appeal to his wife to come home after telling police earlier that he had an argument with her before she disappeared.
"Please give us a call," he said at the news conference. "Let us know what's going on. I know we have a lot to talk to about."
He refused to answer questions, but in an earlier local television interview, he denied any involvement in his wife's disappearance and said police had not asked him to take a polygraph test.
Neither Lyle Herring nor his lawyer responded to messages left by ABCNews.com. One of his colleagues at California State University, Northridge, where he works as a recruiter, told ABCNews.com that he was on administrative leave, but the human resources department refused to comment on what they called an "ongoing personnel matter."
Initially, it appeared that both Herrings were missing.
