When referring (in-text) to a bankruptcy case previously mentioned in a brief, does one need to include "In re"?

For example:

A plaintiff's french fry debts are nondischargeable. In re McDonald . . .

Would I start the following paragraph with:

--Ronald McDonald, the plaintiff in In re McDonald declared bankruptcy...

or

--Ronald McDonald, the plaintiff in McDonald declared bankruptcy...

Thank you.

Not for an in-text cite to a previously mentioned case.
