Prosecutors want Aaron Hernandez jury to hear gun testimony

BOSTON - Prosecutors have asked a judge to allow testimony that former New England Patriot Aaron Hernandez owned a gun similar to the one used to kill Odin Lloyd.

Hernandez has pleaded not guilty to murder in connection with the June 2013 slaying of Lloyd, who was dating the sister of Hernandez's fiancee.

Prosecutors said in Tuesday's filing that Hernandez told a friend weeks before Lloyd's death that he owned a .45-caliber pistol. Authorities allege Lloyd was shot with the same type of weapon.

Prosecutors also asked the judge to bar the defense from calling an expert witness who can describe the effects of the drug PCP on the brain, saying there's no evidence suggesting PCP played a role in the killing.

Hernandez's lawyer did not immediately return a phone message.

Jury selection begins Jan. 9.
