The manager of a Koreatown apartment building came home Sunday and discovered the bodies of his wife, a brother-in-law and a grown son, police said.
The circumstances involving the apparent slayings were being withheld pending an investigation, said Los Angeles police spokesman Don Cox.
Police said the ages of the victims were not immediately known. They were discovered inside the apartment building on South Catalina Street about 6:50 p.m., said Los Angeles Fire Department spokesman Brian Humphrey.
A civilian grief counselor who works with the Fire Department was sent to the apartment building, Humphrey said. It was uncertain whether the counselor was requested to help console family of the deceased victims or neighbors, Humphrey said.
