STOUGHTON, MASS. (WHDH) - A Mansfield woman is set to face a judge Wednesday in connection with the death of a Boston police officer who was found unresponsive outside a home in Canton.

Karen A. Read, 41, is slated to be arraigned in Stoughton District Court on charges of manslaughter, leaving the scene of a motor vehicle collision causing death, and motor vehicle homicide, Norfolk District Attorney Michael W. Morrissey announced.

Read allegedly drove to Fairview Road in Canton with Boston Police Officer John O’Keefe just before midnight Friday. The relationship between Read and O’Keefe is not clear at this time.

O’Keefe, 46, of Canton, was found unresponsive outside a home in that neighborhood early Saturday morning and officials said he appeared to have been outside for some time.

He was transported to Good Samaritan Hospital, where he was pronounced dead several hours later, Morrissey said.
