SHELBURNE, Vt. (WCAX) A Shelburne senior accused of testing poisonous ricin on her neighbors must hand over her cellphone.

Federal authorities got a search warrant for Betty Miller's phone. They are looking for evidence of ricin research, instructions on how to make toxins, plans for a biological attack, names of people she may have tested the ricin on and any information about her travel since June 1.

The 70-year-old previously told investigators she had been interested in ricin for months before she allegedly started making it in her apartment at Wake Robin. She remains in federal custody.
