The embattled lead investigator in the death of Boston cop John O'Keefe has been fired from Massachusetts State Police after an internal investigation.

During the trial, Read’s lawyers accused Proctor of manipulating evidence and conducting a biased investigation. They based that allegation in part on text messages Proctor sent to friends, relatives and supervisors that showed him using offensive and vulgar language to describe Read.

Michael Proctor was fired by Massachusetts State Police Wednesday for his actions in the Karen Read investigation.

Prosecutors asked that police be authorized to use "reasonable physical force" to maintain order around the buffer zone.

The judge in the Karen Read case admonished the defense team on Tuesday for "repeated misrepresentations" to the court, but did not remove any lawyers with less than a month to go before her second trial is supposed to start.
