An official at Glendale Adventist Medical Center said "an important part of the team" was lost when a key nursing director was shot and killed this week in her Van Nuys apartment.
Los Angeles homicide detectives on Wednesday were searching for suspects in the Monday morning death of Sherri Rae Rasmussen, 29.
Police said they believe Rasmussen was killed when she surprised one or more intruders who beat her and shot her once before stealing her car.
Investigators also were searching for the car, a silver two-door, 1985 BMW 318i with the license plate 1MJK850.
The body was discovered by her husband, John, when he returned home from work about 6 p.m. Monday, police said. The couple had been married three months, according to hospital officials.
Hospital spokesman Ken Rozell said Rasmussen had taken a day off work because she had injured her back while doing aerobic exercises.
Rasmussen had been director of nursing of the hospital's 150-bed critical care and surgical units for two years.
Althea Kennedy, vice president of nursing, said: "I can't imagine not working with her. She was such an important part of the team."
