Police on the scene confirmed that a man had died of stab wounds but offered no other details. Blood stained paper towels littered the porch outside the unit.

A stabbing victim was taken from an 'Ewa Beach address to Hawaii Medical Center West in critical condition, emergency medical services spokesman Bryan Cheplic said.

Police and emergency personnel were called to the vicinity of 91-1060 Mikohu Street, the Palm Villas II apartment complex in 'Ewa By Gentry at about 6:30 a.m.

Adelina Cambe, 52, who lives in a townhouse next door to the man she identified as the victim, said she was shaken awake this morning by the sound of a door slamming.

She ran outside and saw her neighbor on the porch in front of his unit bleeding badly from the stomach and crying out for help. Cambe said she also saw a person who appeared to be a woman walking away from the scene.

Tan Chang, 36, who lives next door to the victim, said he woke up when he heard struggling and other commotion coming from the bedroom on the other side of his wall.

He said he called 911 and looked outside, but did not see anything.

Chang said someone who lived in the unit a long time recently moved out and that he hadn't seen his new neighbor.

Cambe said she saw the man she described as the victim several times recently and that he appeared to live alone.

Cambe said she believes he was renting the unit because she knows the owner.

Cambe said, the man once greeted her, saying, "Hi, hello ma'am, how are you?"
