Some law enforcement officers wore wetsuits Monday while searching near both Hernandez's home and the industrial park where Odin Lloyd's body was found.
Lloyd was a 27-year-old semi-pro football player for the Boston Bandits who was found slain June 17.
His family says he was dating the sister of Hernandez's fiancee. They say the two men were friends and were out together on the last night of Lloyd's life.
An Attleboro District Court official said no new documents were available in connection with the case Monday morning.
