The Connecticut chief medical examiner is bringing in a genetics expert to help with the investigation of the massacre at Sandy Hook elementary school.
In the meantime, a stunned local business owner is sharing his eerie encounters with Adam Lanza, who killed 27 people.
Bob Skuba, the co-owner of the Robert Anthony Salon in Newtown, said Lanza was silent and never made eye contact when he had come in with his mother for his regular haircut.
"I would always make jokes with him, trying to make conversation," Skuba said. "He wouldn't say a word. He wouldn't. He would look down to the tile, he wouldn't look up."
Even though Lanza was in his teens, Skuba said his mother appeared firmly in control.
"The only time he would move or make any type of movement is when his mother told him to," he said. "That was it. Those were the only times."
Another stylist at the salon, Diane Harty, who cut Lanza's hair said he made her feel uncomfortable but she never imagined him capable of destroying so many innocent lives.
"You look back and you go wow, he did have, you know, some sort of social problem but you couldn't look back and go 'Oh my gosh, this person could have done this horrible thing,'" Harty said.
The killer's hair may be involved in this story in another way. It could end up helping investigators, who are waiting for toxicology results.
Dr. Michael Baden, Fox News forensic expert, said that better than anything else, a hair sample will reveal what drugs, if any, were in his system over the last year.
Now that they're empty-nesters, Ron Howard and his wife have sold their nest straddling the New York and Connecticut state line for $27.5 million. Howard and his wife, Cheryl, bought the Conyers Farm estate in Greenwich, Connecticut, and Armonk, New York, in 1991 and spent years constructing the house and outbuildings.
