A judge has sealed the investigation documents involving the killing of an acquaintance of New England Patriots tight end Aaron Hernandez.

Attleboro District Court magistrate Mark E. Sturdy issued a statement Tuesday saying that all records related to the shooting death of 27-year-old Odin Lloyd will be impounded.

"All records of the Attleboro District Court Clerk - Magistrate's Office involving the homicide investigation in the Town of North Attleboro have been impounded by order of the Court," Sturdy's statement said. "No further information is available at this time."

ABC News on Friday reported that authorities were expected to execute an arrest warrant at some point for Hernandez for obstruction of justice, but that has yet to occur.

State police officers and dogs searched Hernandez's home for more than 3½ hours Saturday. The results of search warrants normally would be unsealed within seven days.

Michael Fee, an attorney for Hernandez, released a statement Monday night that read:

"Over the past week, our client, Aaron Hernandez, has been the subject of a relentless flood of rumors, misinformation, and false reports in the media. These include the repeated publication of a supposedly confirmed report that an arrest warrant had been issued for Aaron, a report that was exposed as untrue.
