闷死

The killer smothered the victim with a pillow.

杀人犯用枕头了受害者。

The smoke and fumes almost suffocated me.

烟雾差儿把了。

You were strangled to death with a plastic sack. It's probably an odd thing to hear - I wasn't sure how to sugarcoat it.

你确实被个塑料袋套上了。可能着挺怪的，不晓得怎么说才能。

The baby suffocated under its pillow.

婴儿在枕头下。
