Ray McDonald will not be charged with domestic violance stemming from an August incident at his house due to a lack of evidence.

That was the expected outcome after a long investigation, though the San Francisco 49ers do not come out of this thing looking completely clean.

The involvement of a San Jose police officer who worked off duty for the 49ers created an unusual and uncomfortable conflict of interest in the case.

McDonald continued to play for the 49ers while the case was pending.
