Karen Read’s motion to dismiss the murder case against her was filed in Norfolk Superior Court on Wednesday ahead of a second trial in April, court records show. But a copy of the motion was not immediately available because it was impounded,

Prosecutors allege that Read backed her Lexus SUV in a drunken rage into her boyfriend, Boston police officer John O’Keefe, early on Jan. 29, 2022.

In an exclusive one-on-one interview, Read recently told Boston 25 that she has “nothing to hide” and that she’s “been framed” for murder.
