Police find no evidence Connecticut gunman was on medication

While Newtown buried two more young victims Tuesday in the shooting massacre, authorities said they found no evidence the gunman who killed 27 people was being medicated for mental illness.

Investigators searching the Connecticut home gunman Adam Lanza shared with his mother, Nancy Lanza, seized cellphones, computers and computer games, but found nothing at the residence to indicate he was taking medication, Hearst Connecticut Newspapers reported. 

Authorities armed with search warrants are still working to obtain the 20-year-old man's medical records, according to the report. Lanza's parents told friends and divorce mediators that their son had Asperger's syndrome, a form of high-functioning autism, but it was unclear if he had ever been formally diagnosed.

Lanza opened fire Friday morning inside the Sandy Hook elementary school, killing 20 young children and six adults. He shot and killed his 52-year-old mother inside her home before driving to the nearby school. Nancy Lanza was shot four times in the head, likely as she slept, authorities said Tuesday.
