Police arrested a 19-year-old man as a suspect in the stabbing death of a 27-year-old woman early this morning in her apartment in the lower McCully area.

The Honolulu Medical Examiner's office today identified the victim of the fatal stabbing as Lyola Mesebeluu. An autopsy will be conducted to determine the cause of death, according to the medical examiner's office.

The woman's husband, 26, and 2-year-old daughter were injured in the incident.

Police Maj. Alan Blumeke said at 8:30 a.m. that the husband remains in serious condition and the toddler in stable condition with minor injuries at The Queen's Medical Center, where the woman was pronounced dead at 6:10 a.m.

Blumeke said patrol officers were sent at 4:10 a.m. to the three-story walk-up apartment building at 2222 Kapiolani Blvd. on an argument call.

The husband told arriving police officers that he was awakened by his wife's screams. The 19-year old suspect was taken into custody at the scene about 4:30 a.m., Blumeke said.

"As far as we have been able to determine at this point, the suspect and the victims are not related," Blumeke said.

He said the suspect, who was later arrested on suspicion of second-degree murder, "made entry into the unsecured apartment."

Police had not yet determined if the suspect was intending to burglarize the apartment, or what led to the stabbing.

Police homicide investigators were at the building at 8:30 a.m. interviewing other residents and surveying the scene.

Blumeke said a large kitchen knife, believed to be the murder weapon, was recovered at the scene.

As of 5:15 this morning a large number of police were congregated around the apartment building, between Hoawa and Paani streets.

Yellow "crime scene" tape cordoned off the building's parking lot.

Bryan Cheplic, spokesman for the city Emergency Services Department, said paramedics were summoned to a Kapiolani Boulevard address at 4:21 a.m. and treated the three victims. The man and the woman appeared to have multiple stab wounds, Cheplic said.

The woman, who appeared to be in her mid-20s was determined to be in critical condition, while the man, who is about the same age, was transported in serious condition, Cheplic said.

The child, who Cheplic described as a toddler, was reported to be in stable condition with minor injuries.
