A Florida woman charged with threatening the parent of a boy killed in the 2012 mass shooting at Sandy Hook Elementary School in Newtown, Connecticut, was a no-show at change-of-plea hearing.
The lawyer for 57-year-old Lucy Richards told a federal judge Wednesday that she refused to come to court. The judge issued a warrant for her arrest.
Richards lives in Brandon, about four hours from the Fort Lauderdale courthouse.
She was set to plead guilty to a charge of interstate transmission of a threat to injure.
Prosecutors said she believed the Sandy Hook mass shooting was a hoax.
She previously pleaded not guilty to threatening Lenny Pozner, father of 6-year-old Noah Pozner.
Others linked to the Sandy Hook massacre have reported harassment by conspiracy theorists who argue it was staged to erode support for Second Amendment gun rights.
