Daniel Mustard pulled a knife on his mother on March 27, 2009, and started talking with a different voice than he normally uses, according to testimony from Kitsap County Sheriff’s Deputy Timothy Keeler.

Mustard told her he wasn’t her son, but a demon in her son’s body, and that she should wait and see what he would do next.

His parents took him to the emergency room at Harrison Medical Center because of incident, but he wasn’t committed.

Nine days later, Mustard allegedly killed his neighbor, 87-year-old Ruby Andrews.

He pleaded innocent by insanity to the murder, and lawyers in Kitsap County Superior Court this week presented some of their first witnesses to determine his level of psychological competence when he killed Andrews.

They interviewed Ruby Andrews’ husband, 91-year-old Earl J. Andrews, on Monday morning.

On April 5, 2009, Earl left Ruby alone to cook dinner while he went to pick up their adult son, Brian Andrews.

When Earl and Brian got home, between 4 p.m. and 4:30 p.m., Earl noticed right away the couple’s 1993 Cadillac DeVille wasn’t parked in the driveway where he left it.

At first, he thought Ruby took the car to get some special food for Brian.

Then he noticed their neighbor, Willard Means, standing in the driveway.

Means said he saw a man get into the car and drive away shortly before Brian and Earl returned.

Earl went into the house calling Ruby’s name, but he got no response.

He didn’t notice anything in disarray because he “was just looking for Ruby,” he said.

He found her lying on her back in a pool of blood on the floor of her bathroom.

He reached down to touch her hand, and that’s when he “realized that she passed away.”

The Andrews’ neighbor, a nurse, came in and noticed that Earl and Brian seemed to be going into shock.

She told them to leave before they “messed up any evidence,” said Earl.

Lawyers presented that evidence, and other crime-related items to the jury.

They showed Mustard’s shoes, which had spots of blood on them. They showed unusual guns, which Earl Andrews identified as having been stolen from his home.

They showed jewelry, which he identified as belonging to his wife.

The lawyers also interviewed the doctor who performed Ruby Andrews’ autopsy, and he said she received multiple stab wounds through the sweatshirt and blouse she was wearing during the attack.

Several of the knife cuts punctured major organs, several cut her hand as she tried to block the knife and she received blunt force trauma to her face severe enough to dislocate a tooth and break her nose.

Police also interviewed the deputies who collected evidence and interviewed related individuals following the murder.

They talked with Mustard’s girlfriend, and she told them Mustard told her several months before that he’d killed a couple of boys in California.

She thought he was just joking.

Then he told her that he’d killed someone again. This time, a lady.

Again, she thought he was joking.

But when she heard about the murder through the news, she thought she should tell someone what Mustard told her.

Police also talked with Mustard.

At one point, they mentioned the crime scene probably looked pretty gruesome.

Mustard allegedly said, “I’ve seen worse,” and said that he saw three of his friends be tortured and killed while he was held at gunpoint.

During the same interview, Mustard told police he wasn’t a bad guy and that he didn’t commit the murder.

Throughout the trial, Mustard sat at the front of the room looking down, at several points rubbing his eyes.

His parents sat behind him.

Earl Andrews sat through the testimony, on the opposite side of the room as the Mustards.

The trial is expected to last for several weeks.
