The actor, the first to perform Lois Lane, Superman’s girl in the movie, was found dead at her home in Montana on May 13th. At that time, her manager had stated that Kinder died peacefully in her sleep.
However, the forensic scientist in a statement said that the death resulted from “overdose of drugs and alcohol,” which Kidder herself took, without giving any further details.
Kidder struggled with psychological problems for years. She suffered a nervous shock in the 1990s, disappeared for four days, and later diagnosed with bipolar disorder.
