Re-probe or reinvestigation?

"Call strengthens for re-probe into Yuva Morcha leader’s murder," said a newspaper headline.

Re-probe? Wiktionary says "to probe again", but the Corpus of Historical American English did not return any search results for either "re-probe" or "reprobe". Moreover, reprobe seems to be a molecular biology term than a word meaning "reinvestigation". To be more apt, it is better to use "reinvestigate" than re-probe.
