LOS ANGELES — Brittany Murphy, the actress who got her start in the sleeper hit “Clueless” and rose to stardom in “8 Mile” before her movie roles declined in recent years, died Sunday in Los Angeles of what appeared to be natural causes, a Los Angeles County coroner’s official said. She was 32. Murphy was pronounced dead at 10:04 a.m. at Cedars-Sinai Medical Center, hospital spokeswoman Sally Stewart said. Murphy was transported to the hospital after the Los Angeles Fire Department responded to a call at 8 a.m. at the home she shared with her husband, British screenwriter Simon Monjack, in the Hollywood Hills. An official cause of death may not be determined for some time, since toxicology tests will be required, but “it appears to be natural,” Winter said. He said an autopsy was planned for Monday or Tuesday. Winter said Murphy’s family was cooperating with the coroner’s investigation but would not be releasing a public statement Sunday. He said funeral arrangements have not been announced. Detectives and coroner’s officials were at Murphy and Monjack’s home Sunday afternoon but did not talk to reporters. Paparazzi were camped outside the multistory home, located above the Sunset Strip.
