Thank you for the information and your question. If your attorney can establish through your wife's testimony and any physical evidence that the reports submitted by the police were not signed by your wife as agreeing to the facts, then yes, your attorney might have a successful motion to suppress the reports. Or, he or she, can just impeach the testimony of the police, who have to testify anyway since the police reports by themselves could not be introduced as evidence alone since the police are available. They can impeach based on your wife's testimony and, again, any other evidence the attorney has as to their inaccuracies or creation after the fact.
All that said, your attorney is in the best position to know what evidence the State has and how the court
, or a jury, would find credible and a reliable witness. Those are relevant issues and I can't second guess their judgment. I can say that if there is testimony as to your wife's statements immediately after the alleged incident that you had attempted to strangle her and your wife is the only one who can rebut that testimony, then unless this neighbor is totally unbelievable as a witness, the court will likely give more weight to their statement then your wife's.
Ultimately though, this is your decision. If you plead not guilty, the State has to prove the charges beyond a reasonable doubt. But, if you are convicted, of course there will be no chance at a deferral.
Please let me know if you need any clarification. I would be glad to assist you further if I can.
