Man charged with making threats after Newtown shooting likely to plead guilty

NEW HAVEN, Conn. -- A Venezuelan man charged with making threatening phone calls to Newtown residents in Connecticut after the 2012 school shooting is expected to enter a guilty plea, according to court filings.

Wilfrido Cardenas Hoffman has been detained since his June arrest at Miami International Airport, where he stopped in route to Mexico from Venezuela.

Prosecutors have said they will not seek a sentence of more than time served, according to a filing from a dense lawyer for Cardenas. The filing from the lawyer, Jennifer Mellon, said prosecutors agreed to that in light of psychiatric diagnoses the defendant has received and a proposed plan for him to receive treatment in Venezuela.

Cardenas, who is due in court in Hartford on Thursday afternoon, is accused of transmitting threats in interstate commerce, a charge that carries a maximum penalty of up to five years in prison.

On Dec. 14, 2012, Adam Lanza fatally shot his mother and gunned down 20 children and six educators at Sandy Hook Elementary School before killing himself.

Prosecutors say Cardenas made the threatening calls two days after the shootings. Authorities say that in a few calls, he claimed to be the shooter and threatened to kill the person he called.

"This is Adam Lanza. I'm gonna (expletive) kill you. You're dead. You're dead. You hear me? You're dead," the caller said, according to authorities.
