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.

Attorneys in the Karen Read murder case admitted that they paid more than $23,000 to two expert witnesses who testified at trial last year.
