Police that searched Adam Lanza's Connecticut house following the mass murder he is responsible for on Dec. 14 found the 20-year-old's computer hard drive purposefully smashed, making it difficult to remove data, authorities and computer experts told The Hartford Courant.

Lanza allegedly removed his computer disk drive and smashed it into pieces before he made his way to the Sandy Hook Elementary School on Friday in Newton and killed 20 children along with other adults. He also shot and killed his mother in the home they shared together earlier that morning.

Forensic electronics experts at the Federal Bureau of Investigation will examine the hard drive pieces in an effort to determine with whom Lanza corresponded with electronically, what websites he looked at and other details that might explain his motive for shooting the victims at the elementary school, law enforcement sources said.

Officials said Lanza occupied two rooms in his own: one where he slept and another used to store his computer equipment. Connecticut State Police spokesman Paul Vance, said authorities that went into Lanza's home "seized significant evidence" adding that the process of examining that much forensic evidence would be a lengthy and "painstaking process."

The three weapons Lanza used at the elementary school were all legally registered to his mother, Nancy, who enjoyed target shooting as a hobby. Adam visited shooting ranges several times in recent years and went at least once with his mother, according to the Bureau of Alcohol Tobacco and Firearms.

Sandy Hook will not resume classes at least for another month or two, until investigators are finished using the crime scene as part of their investigation. All Newton public schools except Sandy Hook re-opened Tuesday, Dec. 18.

The first funerals for victims of the shooting took place on Tuesday. Two 6-year-olds were buried in Connecticut.
