A man who made threatening phone calls to Newtown residents in the days after the 2012 school shooting rampage has been sentenced to a year in prison.

Wilfrido Cardenas Hoffmann pleaded guilty in December, admitting he made the calls from his home in Venezuela after watching TV news coverage of the massacre.

Cardenas asked for a sentence of time served in light of a need for medical treatment for schizophrenia. Prosecutors didn't make a recommendation on an appropriate sentence.

He was sentenced Thursday in federal court in Hartford.

Cardenas threatened over the phone to kill people following the slaughter of 20 first-graders and six adults at Sandy Hook Elementary School.

He was arrested in June as he passed through Miami International Airport on his way from Venezuela to Mexico.
