The woman was discovered at about 11:30 a.m. in her apartment in the 3100 block of Cowley Way.San Diego police Lt. Kevin Rooney said the woman's boyfriend came to the apartment because he had not spoken with her in a few days and became concerned.Since he could not get inside the apartment, the boyfriend enlisted the help of apartment maintenance workers to open the door. They went inside and found the woman barely alive.She was then rushed to the hospital. At first, paramedics thought she was suffering from a medical problem, but when she arrived at the hospital, doctors concluded that she had suffered major trauma."They said it looks like it was from a blunt instrument to the head," said friend and neighbor Steve Hernandez. Police say the woman is on life support and is not expected to survive.Homicide detectives combed her first floor apartment for fingerprints and other clues, trying to figure out if someone broke into her apartment and attacked her. Her name was not released by authorities. However, neighbors identified her to 10News as 53-year-old Nancy Friberg. "She's a physical therapist and she was just a very friendly, loving person and she and befriended a lot of people here," said Hernandez. Hernandez recalled Friberg's boyfriend, who lives in Coronado, acting strangely over the last couple of days. "Kind of like he was hiding something, kind of scared," said Hernandez. Neighbor Mary Lynn Bonura told 10News, "I just really can't believe something could happen this close to home."Detectives said the woman's boyfriend was questioned and is being treated as a witness, not a person of interest.Anyone with any information is asked to call the San Diego police homicide unit at (619) 531-2293 or Crime Stoppers at (888) 580-8477.
