San Diego

Two elderly San Diego men were found stabbed to death Tuesday in what police believe may have been a double homicide.

The victims, whose names have not yet been released, were found in the 5200 block of Monroe Avenue, near San Diego State University. One victim’s brother discovered the two slain men at 2:30 p.m. when he entered the ground-floor apartment, intending to lunch with his 67-year-old brother.

When the brother arrived, he saw that the screen door was shut and the front door was ajar, police said. He entered the apartment and found his brother lying on the floor next to his bed in his ransacked bedroom, said Lt. Dan Berglund, a homicide detective with the San Diego Police Department.

The slain man was stabbed in the neck and appeared to have been shot in the head, Berglund said. Upon seeing his brother, the man immediately called police, who arrived at 2:40 p.m. Police also found another man, the 71-year-old roommate, in a separate bedroom. It appeared that this man’s bedroom had been locked, and that an intruder had forced the door open, Berglund said. The elderly roommate was stabbed repeatedly in his lower chest, Berglund said.

Police were uncertain about the motive.

“Initially, we thought it might be a murder-suicide, but right now it appears to be a double homicide,” Berglund said.

One neighbor heard loud noise and commotion the previous evening about 11 p.m., he said. Both men apparently worked for a car-rental company, helping to transport cars. They had lived in their apartment for about 18 months.
