In Genesis 37:33, Jacob sees the torn robe and says 'Joseph is torn to pieces'—the exact phrase repeated here, confirming the assumption.

In Genesis 42:13, the brothers first tell Joseph that one son is no more — the same report Judah now retells in his plea.

Genesis 45:26 reverses the claim: Joseph is alive and ruling. The earlier certainty of death is overturned by the news of life.

Genesis 42:36 has Jacob lamenting 'Joseph is no more'—this captures his grief and the belief that drove the 'torn to pieces' conclusion.

Genesis 42:38 shows Jacob fearing that losing Benjamin would bring his gray head down to Sheol—the same desperate context as the loss of Joseph.
