The New York City Office of the Chief Medical Examiner has determined that actor Michelle Trachtenberg died from complications related to diabetes mellitus. She was 39.

Trachtenberg was found unresponsive in her Manhattan apartment on February 26. Emergency medical personnel arrived on the scene and pronounced her dead. Authorities reported no signs of foul play.

Initially, the medical examiner did not perform an autopsy, citing a request from the family based on religious considerations. In the absence of criminal suspicion, the office allowed the request. A final ruling was made following analysis of laboratory samples, which confirmed the cause of death.

At the time of her death, NBC News reported that Trachtenberg had recently undergone a liver transplant. The medical examiner’s statement did not mention that procedure in its ruling.

Trachtenberg began acting professionally in early childhood. Her career started with television commercials and a recurring role as Lily Montgomery on All My Children.
