Trying to find the name of a movie I believe was made in the 1930's or 1940's in which a man murders an old woman and cements her into a fireplace.I remember seeing this movie only once about twenty years ago.

Was she cemented upstairs in an attic?

Sounds interesting.
Haven't been able to find, but do recommend a movies called the "The Big Clock" 1948

Cool murder movie of the 40's.

No she was in an old vehicle, over the cliff and a lot of logs came tumbling on the car. No chance of survival.

My original question was... does anyone remember an old black and white movie I saw back when I was a teen (1970's) Movie was probably 1930-1948 era.
A detective's friend is killed by her husband and in order to get a confession they had a lady about the same size and age to keep appearing at odd places -getting on a bus, sliding into a dress store and he only glanced her...
Finally, this led him to confess...

Good movie, wish I knew just one actor or part of the name...
