The unnamed agent was also cleared by an FBI internal review of the shooting, which occurred at the end of a lengthy interrogation into Todashev's relationship with alleged Boston marathon bomber Tamerlan Tsarnaev, and his purported role in the Waltham triple murders of 2011.
According to the reports, Todashev was in the process of writing a confession to the Waltham homicides when, for no apparent reason, he 'flipped out' and propelled a coffee table into the air, striking the agent on the back of his head. He then ran to the kitchen area of his apartment and armed himself with a red pole/broom handle.
Curtis Cinelli, a 42-year-old State Trooper assigned to the Massachusetts Violent Fugitive Apprehension Unit who was also present during the incident, said he thought he was about to be impaled and was in fear for his life. The unnamed agent then shot Todashev several times resulting in his death.
Prior to becoming a federal agent, Aaron McFarlane was employed as a beat officer with the City of Oakland Police Department, California.
McFarlane first came to the attention of others when he testified in the now infamous 'Riders' case of 2003.
Three officers, Clarence Mabanag, Jude Siapno, and Matthew Hornung, stood accused of 26 counts that included kidnapping, assault, conspiracy, false arrests, and lying in police reports to cover their tracks. The alleged activity of the officers came to light after a colleague, Officer Keith Batt, complained about the group's brutality and abuse of civil rights. A fourth officer, Francisco Vazquez, said to be the group's ringleader, fled the country after charges were filed against him.
Aaron McFarlane testified in defense of Clarence Mabanag, stating that he had always taught him how to write accurate police reports. However, under cross-examination it was alleged that McFarlane had falsified his own reports at the request of the group's leader. Prosecutor David Hollister presented McFarlane with the reports in court, which appeared to contradict his earlier testimony.
After an uncomfortable exchange between the two, Aaron McFarlane went from defending Mabanag, his former field training officer, to invoking his constitutional right to remain silent.
Jurors failed to reach a verdict on the majority of the charges against the three and they were tried a second time, with a similar result. After five years and two mis-trials, District Attorney Tom Orloff said that although he was 'convinced of their guilt' he would dismiss the charges as he did not believe a jury would convict them.
McFarlane was never charged in connection with falsifying police reports or for potentially telling untruths on the witness stand.
Girard stated he had been stood near the entrance to Highland Hospital, Oakland, California, when he witnessed McFarlane and Nowak physically beating an individual who had already been subdued. Girard took a photograph of the incident as it took place and, when McFarlane and Nowak realized that, they attacked him.
The plaintiff alleged he was beaten, kicked, and punched around the body, suffering injuries to his shoulder, arm, knee, and neck. He claimed he was then falsely arrested by McFarlane and Nowak.
The case was eventually dismissed when the City of Oakland Police Department paid Robert Girard a $10,000 settlement.
Neither McFarlane or Nowak faced charges over the incident, even though Nowak had a long record of police-misconduct suits filed against him. In fact, as of 2004, Oakland PD had paid out just under seven-million dollars in relation to suits specifically naming Nowak as a defendant.
Michael Cole's claim was settled with a $22,500 payout. It is unclear if the incident was connected to Robert Girard's case. Again, neither McFarlane nor Nowak faced charges over the incident.
Aaron McFarlane retired from Oakland PD in 2004, on a pension of $50,450,76. He had served at the Department for just four years.
