Honolulu police are investigating a connection between the killing of a woman found in a Young Street apartment Wednesday and a man who died in a fiery crash Monday on the North Shore.

Court documents show that a man received a speeding ticket last year while driving a vehicle with the same license plate of the SUV that crashed Monday. Police suspect the same man was behind the wheel Monday.

Police also suspect the 30-year-old woman found in the Young Street apartment was the wife of the man killed in the crash.

Neither victim has been positively identified by the Hono-lulu Medical Examiner’s Office.

Police reported conducting a welfare check on the woman’s apartment and discovering her body at about 3:30 p.m. Wednesday.

Officers opened an unattended-death case, but but the case was later reclassified to murder.

Autopsy results were not available Thursday.
