Don't hold your breath, is basically the advice of Connecticut's chief medical examiner to anyone expecting science to provide insight into the mind of Adam Lanza. Toxicology and genetic testing is ongoing, but the autopsy H. Wayne Carver II conducted found no "gross deformity" or tumors in the brain, reports the Connecticut Post. "It's a fishing expedition," says Carver. "I don't think we'll find answers."
He adds that he didn't expect to find such a deformity, which would generally indicate a disability so severe custodial care would be needed. Carver also said that Lanza did not appear to suffer from Fragile X syndrome, which is classified as "the most common known genetic cause of autism or autism spectrum disorders." One of the telltale signs of the gene mutation is a large forehead or face; "we measured his head and it fell in the normal range," Carver said. It will take several weeks for the drug tests to be completed. (Read more Adam Lanza stories.)
