A motion to stay a wrongful death civil trial against Karen Reed of Mansfield was granted Friday by a Superior Court judge. 

She's accused of killing her boyfriend, Boston police Officer John O'Keefe, in January, 2022, after a night of drinking.   

His family filed a wrongful death lawsuit in August, blaming Reed for his death, as well as two bars in Canton, claiming they over-served alcohol to O'Keefe the night he died. 

Her first trial ended in a hung jury, and she's scheduled to be retried in January. 

In his ruling, the judge said Reed could not be involved in civil and criminal trials at the same time.
