Following yesterday’s release, today the Dallas Police Department received a complaint of a domestic violence assault that occurred in Dallas on January 30, 2016. A criminal investigation into the incident, in which Johnathan Manziel is the listed suspect, has been initiated. Detectives will thoroughly investigate the case to determine what criminal charges, if any, will be filed and victim services will be offered.
