As investigation continues in the Sandy Hook Elementary School shooting in Connecticut, authorities revealed that Adam Lanza, 20, planned his shooting at the Newton school and rigged his rifle to give him the maximum amount of firepower possible, according to The Telegraph.

Lanza taped two cartridge magazines to his Bushmaster .223 calibre rifle so he could reload as quickly as possible and continue his killing spree. The technique, known as "jungle taping," explains how he managed to kill 26 victims at the school in matter of minutes, Wayne Carver, the Connecticut medical examiner, said.

Metro reported Tuesday that the company whose Bushmaster rifle was used in the school massacre will be immediately put up for sale following investors' concerns, its private equity owner Cerberus Capital Management LP said. Freedom Group Inc., owner of Bushmaster Firearms International that makes the rifle, came under public attack following the Newton, Conn., shooting.

Lanza was found dead with three weapons at the elementary school on Dec. 14, after he killed 20 children and six adults before taking his own life. He broke into the school by shooting bullets through a secured door.

Authorities entered his home soon after and found a room full of his computer equipment that they are now analyzing in hopes of finding a motive for the horrific killings. His computer hard drive was purposefully smashed, making it difficult to remove data, but law enforcement sources said a team of forensic electronics experts will examine the hard drive pieces in an effort to determine Lanza's motive, what websites he looked at and any other details that might help the investigation.

Lanza was reportedly addicted to violent video games that he would play at the home he shared with his mother Nancy, whom he killed before making his way to the elementary school on Friday morning. Investigators also revealed that a special team of criminal psychologists are focusing on Lanza's relationship with his mother, the publication noted.

The weapons Adam used in the shooting were all legally registered to his mother, who enjoyed target shooting and would sometimes practice with her son.
