Honolulu police arrested a 41-year-old man as homicide detectives investigated the apparent beating death of a 33-year-old man and the assault of a 38-year-old woman in Salt Lake Tuesday.

Homicide detective Peter Boyle said a weapon was recovered at a Salt Lake home, but declined to say what it was. Both the dead man and woman had “blunt force injuries,” Boyle said.

Boyle said that Salt Lake patrol officers responded to a report of an assault at a Salt Lake home at 5:06 a.m. and found the 33-year-old man lying in  the middle of Salt Lake Boulevard.

Paramedics took the 33-year-old man in “extremely critical” condition with facial injuries to the hospital, where he later died. The 38-year-old woman went to the hospital in serious condition with head injuries.

Boyle said the incident started with an argument in the Salt Lake home and ended in the roadway.

He said the suspect and victims were not related, but he didn’t know the relationship of the three, except that one of them lives in the Salt Lake house.

Police are also interviewing two-teenaged girls who also live in the home.

Honolulu police closed Salt Lake Boulevard between Likini Place and Wanaka Street as they conducted a murder investigation and reopened the road at about 9 a.m.

Traffic investigators and the department’s helicopter also responded to the scene. Police plan to take aerial photographs of the crime scene,  Boyle said.
