Testimony at a hearing for Aaron Hernandez enters its third days as lawyers seek to have some evidence in his murder case thrown out, including from a cellphone and home surveillance system.

The defense says the former New England Patriot was unlawfully questioned when state police investigating the killing of Odin Lloyd executed a search warrant at Hernandez's home.

They maintain he was not free to leave. He has said he felt "helpless" and worried about his family. Hernandez had earlier referred questions to his attorney.

Hernandez has pleaded not guilty in the 2013 death of Lloyd, who was dating Hernandez's fiancee's sister.

A trooper testified Wednesday that Hernandez didn't seem frightened or raise concerns during the searches and said he could have left. Sgt. Paul Baker's testimony continued Thursday.
