YOLO COUNTY —

The jury found him guilty, but did 17-year-old Daniel Marsh know that stabbing an elderly couple to death was wrong?

Today began the sanity phase of the trial in Yolo County. Psychologists who examined the Davis teen weighed in on whether Marsh knew right from wrong.

At his mother’s house in South Davis, no answer to our knock on the door.

But people in this community, where 87-year-old Oliver Northup and his 76-year-old wife Claudia Maupin once lived so happily, had a lot to say.

“I don’t see how it serves anyone to allow him to go out and do that again. He expressed enjoyment with what he did,” said neighbor Susan Waldo.

Catherine Harrington is a Davis resident and special education teacher who works with severely disturbed children.

“I’ve worked with kids like this. This is really where you have to talk to the psychiatrists and they have to examine him very carefully. Because, there are kids where unfortunately at a young age we need to make tough decisions for the rest of society,” Harrington said.

This tough decision, she says, might just mean locking Marsh up for life for a crime he committed before he was even old enough to drink.
