Newtown Shooter's Computer Badly Damaged A computer at the Connecticut home where Newtown, Conn., school shooter Adam Lanza lived with his mother was badly damaged, perhaps smashed with a hammer, said police who hope the machine might still yield clues to the gunman's motive. The computer's hard drive appeared to have been badly damaged with a hammer or screw driver, law enforcement authorities told ABC News, complicating efforts to exploit it for evidence. Officials have "seized significant evidence at [Lanza's] residence," said Connecticut State Police spokesman Paul Vance, adding that the process of sifting through that much forensic evidence would be a lengthy and "painstaking process." Authorities also told ABC News that the weapons used in Friday's rampage at Sandyhook Elementary School, which left dead 20 children and seven adults including Lanza's mother Nancy, were purchased by his mother between 2010 and 2012. According to the Bureau of Alcohol Tobacco and Firearms, Lanza visited shooting ranges several times in recent years, and went at least one time with his mother. The first funeral for a child killed in the massacre was held today in Fairfield, Conn., where mourners gathered to remember the too-short life of first-grader Noah Pozner. Authorities also revealed this morning that two adult women shot during the rampage survived and their accounts will likely be integral to the investigation. Officials had previously mentioned just one adult survivor. The town of Monroe has offered to open to Sandy Hook students the Chalk Hill School, a former middle school that currently houses the town's EMS and recreational departments. Officials in Monroe, less than 10 miles from Newtown, say the building could be ready for students by the end of the week, but have not yet set a date to resume classes. Nearly 100 volunteers are working to ensure the building complies with fire and security regulations and are working to retorfit the school with bathroom facilities for young children. "We're working to make the school safe and secure for students," said Monroe Police Department spokesman Lt. Brian H. McCauley.
