Medical examiner seeks genetic clues to Newtown shooting suspect Adam Lanza motive

HARTFORD, Conn. - Connecticut's chief medical examiner said he's seeking genetic clues to help explain why a shooter killed 20 children and six adults in Sandy Hook Elementary School in Newtown.

Dr. H. Wayne Carver told The Hartford Courant that he wants to know if there is any identifiable disease associated with the behavior of the suspected shooter, Adam Lanza. Carver is working with the University of Connecticut department of genetics.

Paula Levy, a mediator who worked with Lanza's parents said Lanza had been diagnosed with Asperger's syndrome, an autism-like disorder.

Carver said Asperger's is not associated with violent behavior. He said he's not considering it as a reason for Lanza's rampage on Friday.

Carver is awaiting toxicology testing results for Lanza and other information.

Lanza reportedlty fatally shot himself as first responders approached the school Friday morning.
