LIHUE >> A 34-year-old man charged with fatally stabbing his mother while she was working at a bank last month has pleaded not guilty. Louis Landsman is charged with second-degree murder in the death of Charlene Landsman, 69. He appeared in a Lihue courtroom Thursday but was taken back to a holding cell following an outburst when his request to speak was denied, the Garden Island reported.

“Why, why, why is this happening, why?” Landsman yelled during the hearing. The court excluded Landsman from the rest of the hearing following the disruption.

Defense Attorney Melinda Mendes requested her client undergo an examination to determine his fitness for the legal proceedings. Chief Judge Randall Valencian approved the request and a hearing on the results is scheduled for August.

Landsman was arrested after stabbing his mother at First Hawaiian Bank in Lihue on May 17. On the day of the attack, he visited the bank three times, according to testimony. After the first visit, Charlene Landsman told co-workers to call police if her son came back, but she canceled the call request when he returned. The stabbing occurred on the third visit.
