According to the police report, Rose and his wife were arguing about their marriage when Rose allegedly grabbed her by the face and pulled her closer to his face while he screamed at her. Rose's wife then called 911 but Rose took the phone to stop her from filing a report. Rose later admitted to police that he took the phone, which resulted in the felony tampering with a witness charge.

This is an absolute disaster for the guy. It appears that the argument biggest factor was due to Adam imminently getting fired from the WWE if it wasn't done so already. Gosh, if there was any glemmer of hope such as going back to nxt, all hope has now been eradicated as his wife calling the police definitely sealed his WWE wrestling career fate. Poor Adam. Absolute disaster.
