Trauma

Trauma is a 1962 American film directed by Robert M. Young and starring Lynn Bari and John Conte.

Eight years after her aunt Helen Garrison is killed, newlywed niece Emmaline and husband Warren return to the home where Helen died, where Emmaline tries to recall events from that fateful night that her mind has blacked out.

Suspicious figures lurk throughout the house, and even Warren ends up placed under arrest by treasury agents. It ultimately turns out that Luther, a caretaker, committed one murder years ago, then killed eyewitness Helen to ensure her silence.
