Additional handwritten calligraphic notes and other items recovered from the home of accused triple murderer Adam Mau-Goffredo suggest he planned the shooting of a taxi driver at Tantalus Lookout last year, a detective testified yesterday.

Also recovered during a police search of Mau-Goffredo's 10th Avenue residence were several photographs that indicated Mau-Goffredo was "looking at taxicabs," Detective Roland Takasato said.

Takasato testified at a hearing on a request by Mau-Goffredo's lawyers to throw out the materials recovered at the defendant's 10th Avenue home four days after the shooting deaths of taxi driver Manh Nguyen and bystanders Jason and Colleen Takamori of Kapahulu at the scenic lookout the evening of July 6 last year.

Police had obtained a search warrant for the home based on calligraphic handwritten notes recovered from a car that Mau-Goffredo was driving when he was arrested later that night.

The notes showed some planning was involved in the shootings and listed a "time frame" of 6:45 to 7 p.m. for the death of the taxi driver, according to police. Witnesses reported the shootings just after 7:15 p.m.

Mau-Goffredo's lawyers are contending that the warrant was too broad in violation of the defendant's constitutional rights.

Takasato, who prepared the request for the warrant, said during the hour to an hour-and-a-half search, police were seeking evidence of any planning by Mau-Goffredo, his mental condition and any evidence of the crimes. Among the items seized were photographs, DVDs and CDs, more calligraphic handwritten notes and hardback and paperback books.

The detective said some of the books had calligraphic notations.

Although he wasn't sure if they were from the handwritten notes or notations in the books, Takasato said he believes there were "some writings that spoke of some planning."

He said he couldn't quote it verbatim, but the notes were about "destruction and mayhem, that sort of thing."

The detective was not asked to further elaborate on the notes or the several photographs referring to taxicabs.

The hearing before Circuit Judge Dexter Del Rosario will resume Jan. 19.

After the issue is resolved, Del Rosario is expected to appoint three mental health experts to examine Mau-Goffredo as a prelude to an insanity defense.

Mau-Goffredo, 24, who has been diagnosed as a paranoid schizophrenic and is being held at Halawa prison, did not say anything during the hearing but sometimes glanced upward and appeared to smile to himself.

He wore the orange Halawa prison uniform and slippers, his ankles and wrists in shackles. His head was shaved when he first appeared in court last year, but he now has a head of hair and a fuller beard.

Mau-Goffredo also appeared to have lost weight.

"I'm concerned about whether he's healthy," his lawyer, Brook Hart, said.

In addition to the murders, Mau-Goffredo is also charged with the home-invasion robbery of a nearby home after the shootings. He faces charges that include first-degree murder, kidnapping and armed robbery.

No trial date has been set.
