Why did Ethan Russell do this in the movie "The Woman in the Window" (2021)?

I have recently watched the movie "The Woman in the Window" (2021) with Amy Adams. I probably missed something, because I do not understand why the son, Ethan Russell (played by Fred Hechinger), killed Jane Russell 1 (a.k.a Katie, played by Julianne Moore). What was his motive?

Thank you for your explanation and help.

It wasn’t all in her head. Anna Fox, the former therapist suffering from agoraphobia, who regularly drank too much alcohol with her medication, did in fact witness a murder in her neighbors’ house; but neither the victim nor the murderer was who she thought. The "shocking" twist that the Russells' teenage son Ethan was the murderer was likely only a surprise to Anna, as Ethan was super creepy and suspicious throughout the movie. And the victim was not Jane Russell, as Anna kept insisting, but Ethan’s biological mother Katie.
