(CNN) -- The stepmother of a missing 10-year-old North Carolina girl joined police as they searched for the girl's body Monday, the same day the girl's father landed behind bars.

Elisa Baker, who police said last week admitted to writing a fake ransom note a day after the girl's disappearance was reported, was taken by police to a search site near a home she lived in three years ago, according to CNN affiliate WSOC.

Earlier on Monday, shortly after 3 a.m., Adam Troy Baker was arrested in Catawba County on eight charges, including five counts of submitting worthless checks and three counts of failing to appear in court.

Police earlier acknowledged that Adam Baker faced bad-check charges, which are unrelated to the disappearance of his daughter, Zahra Clare Baker. But they did not initially arrest him, as he had been helping authorities in their search.

Zahra was reported missing October 9. But no one other than a family member has reported seeing her since September 25, when a woman saw her at a furniture store.

Elisa Baker was arrested on October 10, initially on several charged unrelated charges, including writing worthless checks. Last week, she was additionally charged with obstruction of justice -- a felony -- after leaving the ransom note at the family's home.

Authorities on Friday ended an unsuccessful search at a North Carolina landfill for a mattress connected to Zahra's disappearance, said police in Hickory.

The adolescent's disappearance is being investigated as a homicide, police said. Local, state and federal authorities, along with cadaver dogs, are continuing to search Caldwell County and thereabouts for signs of Zahra.
