Former New England Patriots tight end Aaron Hernandez says in a court filing he felt helpless and concerned about his fiancee and their baby when police investigating a 2013 killing questioned him during a warranted search at his home.

Hernandez has pleaded not guilty to murder in the June 2013 fatal shooting of semi-professional football player Odin Lloyd of Boston.

His affidavit released Tuesday is part of a motion to suppress evidence related to his cellphone, which he told police how to access.

Hernandez said, ``I felt helpless in the face of the occupation of my house by the police.'' He said he was concerned about what would happen to his fiancee and baby if he didn't answer police questions during the search.

Hernandez's lawyers say he should have been given a Miranda warning.
