Man with ties to Aaron Hernandez appears in Suffolk Superior Court

A man with ties to former New England Patriots tight end Aaron Hernandez visited a Boston courthouse Thursday after being ordered by a judge to testify before a Massachusetts grand jury. John Alcorn of Bristol, Conn., arrived at Suffolk Superior Court shortly after 9 a.m., accompanied by his attorney, Matthew Dyer. Dyer declined to comment as he entered the building with his client. Alcorn, 21, is related to Thaddeus Singleton III, the deceased husband of Tanya Singleton, a cousin of Aaron Hernandez, said Lieutenant Kevin Morrell of the Bristol police.
