It appears that the wait for charges has been a mere technicality as Hector Olivera will be formally charged
The wait for Hector Olivera to actually be charged in the case that broke this morning has led to some interesting speculation whether the witness/victim was cooperating. Given that the police investigations/charges against MLB players Aroldis Chapman and Jose Reyes were dropped before the commissioner's office could act in addition to the amount of money involved makes building a case in these situations far from easy.
However, it does appear as though, for the moment, Hector Olivera will be formally charged this afternoon
UPDATE on Hector Olivera from source: likely make first appearance in court at 3-4 today; likely be charged w/ misdemeanor assault & battery

One cannot read to much in to the felony/misdemeanor distinction in these cases this early.
