Need input urgently

Last week on Thursday January 11th at 2:20 I was doing my last rounds and my dsd passes by me and tells me we needed to talk. She pulled me into a utility closest (where employees regularly go in and out) and tells me I need to clock out there's an allegation of abuse. Naturally I was shocked and started crying she refused to tell me my allegations and told me to leave and assured me no one knows I'm being suspended. Mind you the utility closet is right next to the nurses station where all my co workers seen me leave crying and upset. The next day in the morning meeting they told all cnas there's allegations of abuse. The weekend pass and Monday I go an hear my allegations give a statement, someone who reportedly helped me with a resident is saying I was verbally abusive towards the resident because I was allegedly rushing my resident. How ever that person statement is saying it happened on a day I wasn't even assigned to a resident and the days I did have the resident there was only two people who helped me with the resident and the administrator stated it wasn't either person who reported me and if I could think of anyone else who might of helped me with him. What upsets me is when I quickly stated I hadn't even gone into the room with that resident on Wednesday my dsd was quick to say well maybe he got the day mixed up and said it must've been Monday. If I abused the resident Monday how come that person waited until Thursday to report it when it needs to be reported with in 24 hours and the resident who I "abused" is very oriented and is not shy about reporting cna's for whatever reason. So if I was so abusive why didn't he express any concerns. I also wanna know when I got suspended was I suppose to be brought into her office with another department head, instead of being humiliated and also shouldn't my dsd have done more investigation and why couldn't she just ask the resident himself? Why is she listening to someone else word off the bat? Input, and opinions are greatly appreciated
