Sheriff's spokeswoman Kelly Hoover says Paula Lopez was reported missing by concerned family members on Wednesday morning, and they contacted authorities at about 5:30 p.m. to say she was home.
Hoover declined to comment on the reasons surrounding Lopez' disappearance, citing a private family matter.
The 48-year-old Lopez is a co-anchor of the 11 p.m. newscast at the ABC affiliate, where she has worked since 1996. Before that, she worked at KCAL-9 in Los Angeles for six years, according to her online biography.
Deputies, two K-9 units and a helicopter searched for Lopez, along with detectives and search and rescue personnel.
