Double Check then Triple Check Before Hitting 'SEND'

A well-intentioned candidate sent me his resume for a recently posted job. When I opened the attachment, the document was under someone else's name and for a completely unrelated position! Just because the cover letter indicated that this might be a decent candidate, I wrote asking for the correct resume. The next email contained a polite apology and an empty attachment. Should I send another email to the candidate? I need a few to weigh in with your opinions. Please write to me!!!
