The Chronicle reports (http://bit.ly/1NgIYmV) it received the email Tuesday. The person wrote that 29-year-old Denise Huskins would be returned safely Wednesday and would be "in good health and safe."
The email also warned any attempt to find the people holding Huskins would "create a dangerous situation" for her.
Huskins' boyfriend on Monday reported to police that she'd been abducted from their Vallejo home. She was found 400 miles away in Huntington Beach.
Her father says she was dropped off at her mother's home, then walked to his home 12 blocks away.
