BOSTON -- Family members of the man found slain a mile from New England Patriots tight end Aaron Hernandez's house said Friday they are looking for answers about what happened the night he died.

Police have searched in and around Hernandez's sprawling home in North Attleborough, not far from where the Patriots practice. The Bristol County district attorney has not released any information other than saying the death of 27-year-old Odin Lloyd is being treated as a homicide.

Massachusetts authorities are expected to execute an arrest warrant at some point for Hernandez for obstruction of justice in connection with a homicide investigation, sources told ABC News on Friday.
