Piecing Together A Portrait Of James Holmes

As new developments unfold about accused killer James Holmes, INSIDE EDITION spoke with one of his former teachers and paints a picture of Holmes' past.

Cell phone video captured the walk up to accused mass killer, James Holmes', third-floor apartment.

Red police tape seals the door and hand-written signs read, "No Trespassing" and "Do Not Enter." The door handle is gone, keeping the apartment secure are two padlocks bolted into place.

Meanwhile, INSIDE EDITION has uncovered a very different image of James Holmes.

Before he was the orange-haired accused psycho killer, he was little Jimmy Holmes, with Harry Potter-esqe round glasses and a squeaky-clean haircut.

Paul Karrer was Holmes' fifth-grade teacher at Castroville Elementary School outside Monterey, California.

Karrer said, "He was a great student."

He told INSIDE EDITION he saw no sign of a monster lurking within.

"I can remember he was clean cut. I remember he was very positive, happy kid," said Karrer.

As the heartache from the tragedy continues, the question swirls - what do we tell our children?

Dr. Mary Pulido is the Executive Director of the New York Society for the Prevention of Cruelty to Children.

She said you should focus on the heroics that the tragedy inspired.

Dr. Pulido said, "Look at how the first responders, the police, the firemen, the medical personnel rallied. The people inside the theater rallied to help carry people out."

Dr. Pulido also stressed the importance of reassuring your children they're secure.

INSIDE EDITION's Diane McInerney asked, "What if your child is afraid to go to the movies now?"

"I think that what parents should do, probably in steps, is take the child to the movie theater. When they are ready to go, say 'I'll go with you.' Your children may feel comfortable sitting in the back where they can get out quickly the first time they go back," said Dr. Pulido.
