Police again search Aaron Hernandez's home
State police officers and dogs searched the home of New England Patriots tight end Aaron Hernandez again Saturday as they continue to investigate the killing of a semipro football player whose body was found about a mile away.
The search of Hernandez's sprawling home and vehicle in North Attleboro, Mass., began in the afternoon and lasted for more than three hours. Locksmiths and several officers were involved, including one with a crowbar.
Detectives and uniformed officers who searched the home, its backyard and playhouse did not comment to reporters on what they were looking for or what caused them to return to the house located not far from where the Patriots practice and about a mile from where a jogger found the body of Odin Lloyd on Monday.
Lloyd family members said Friday that he had been dating the sister of Hernandez's fiancee for about two years. They said the two men were friends who were together the night Lloyd died.
Police previously searched in and around the home as they try to figure out who killed Lloyd.
