Honolulu police found human remains today inside a Waikiki apartment of a murder suspect.

Homicide Lt. Phillip Lavarias of the Honolulu Police Department said officers executed a search warrant at the residential building at 414 Launiu St. just after 6 a.m. today and discovered the remains.

The remains were transported to the Honolulu Medical Examiner’s Office.

Lavarias declined to disclose where the human remains were located within the apartment and whether the body of the woman is the suspect’s mother.

Detectives are interviewing witnesses to determine when the victim was last seen.

Police arrested a 26-year-old man Tuesday morning on suspicion of second-degree murder after he called 911 and said he was suicidal and that he killed his mother a year ago.

According to the University of Hawaii, the suspect attended Kapiolani Community College from fall 2011 to spring 2016. He also registered for classes at Honolulu Community College in 2014.
