June 17: The body of 27-year-old semi-pro football player Odin Lloyd is found around 5:30 p.m. in an industrial park a mile from Aaron Hernandez's home in North Attleboro, Mass. Investigators discover Lloyd was dating the sister of Hernandez's fiancé.
June 18: A Nissan rental car is connected to Lloyd's death — its keys were found in his pockets, and his sister describes seeing him enter the vehicle. Police find that the car was rented in Hernandez's name. Officers enter his home (ostensibly with his permission, since the issuance of a search warrant isn't reported until later in the week). Another group of officers search the industrial park. Two individuals are taken in for questioning at Hernandez's home.
June 19: Lloyd's death is ruled a homicide by a state medical examiner.
June 20, 11 a.m.: Police say they haven't ruled Hernandez out as a suspect in the murder. A news helicopter begins following him around.
June 20, afternoon: News breaks that Hernandez attempted to destroy his security system and cell phone and hired a house-cleaning service just hours before Odin's body was found.
June 21: An arrest warrant is issued for Hernandez for obstruction of justice in connection to the homicide investigation. Investigators learn that Hernandez and Lloyd were together the night Lloyd died. Homicide detectives search a Providence, R.I., strip club and obtain its surveillance video. The New England Patriots reportedly tell Hernandez to stay away from the team's facilities.
June 22: Law enforcement officials enter Hernandez's home with a warrant and leave with several bags of evidence around 5 p.m.
June 23: Officers search the woods near Hernandez's home.
June 24: Hernandez's attorney says his client has been the subject of "rumors, misinformation, false reports in the media." Law enforcement officers in wetsuits search near both Hernandez's home and the industrial park where Odin Lloyd's body was found.
June 26, 8:45 a.m.: Hernandez is arrested outside his home and taken for booking.
June 26, 10 a.m.: Hernandez is released by the Patriots, who say in a statement, "At this time, we believe this transaction is simply the right thing to do."
June 26, 2:45 p.m.: Hernandez is charged with murder and several counts of unlawful possession of firearms. He pleads not guilty and is held without bail.
UPDATE: Aaron Hernandez is now being investigated for his possible involvement in an unsolved double homicide, which occurred in Boston in 2012.
