Mid 70s Horror Movie

[hotspur]

I was too young to see it, but I remember a movie being advertised in the mid 70s that was a horror movie.  I think the idea was that one person (likely a child) was evil and killing off his relatives.  In the trailer they showed one person being sealed in a room, with voice over saying he (the villain) gave them (the victim) a room of his own and another scene where 2 people are crushed together in a shower.  Any ideas?

nothing springing to mind... I guess PSYCHIC KILLER ticks a few of those boxes. not child though.

I was wondering if this was ARNOLD from 1973?

The "room of his own" and "the crushed in a shower" scenes are in this trailer.

I watched ARNOLD earlier this year, and those scenes match - but Arnold is a 70 year old corpse, not a child!

That's it!  Thank you.  I remember being so freaked out by that trailer, and seeing it now is pretty funny.
