Web search results confirm that Judge Gregory Carro was scheduled to rule on whether evidence from the backpack should be suppressed, but the provided evidence does not explicitly confirm the final ruling that he 'blocked' the evidence on that specific Monday. The evidence shows the hearing was pending or expected.

The provided evidence for this claim consists of Wikipedia entries for the video game character Luigi and a jazz dancer, which are completely irrelevant to the legal case of Luigi Mangione. No evidence regarding a McDonald's in Pennsylvania was provided in the search results.

While web search results confirm Judge Gregory Carro was presiding and considering a bid to suppress evidence (including a pistol and journal), the specific quote and the detailed list of suppressed items (magazine, cellphone, passport, wallet, computer chip) are not explicitly corroborated in the provided evidence snippets.

The evidence confirms that prosecutors argued for the admission of evidence from the backpack and that a journal was among the items mentioned, but there is no specific confirmation in the provided text that Judge Carro ruled the journal specifically was admissible while others were not.
