ROCHESTER, N.Y. -- Tuesday marks the one year anniversary of the death of Richard "Greg" Davis.
Rochester police say the 50-year-old man was involved in a number of hit and run crashes on Tremont Street on May 31st of last year.
Police say he did not obey orders to remain in his truck and instead charged at police with his fists clenched.
That's when authorities tased Davis.
The Medical Examiner ruled his death as a homicide.
They also found Davis had cocaine in his system and suffered from high blood pressure and heart disease.
Last week an investigation found that the officer's actions were justified.
Now, a year after his death, Davis's family reacts to the DA's decision.
"We expected that. We were not surprised that they came up the decision that they came up with," Richard's sister Andrea Davis said. "That's why as a family member, we want to thank the coroner's office of Monroe County for speaking for our brother and coming up with what they came up with as what it was, a homicide. They spoke for my brother when he couldn't speak for himself. So again, as a family, we aren't angry about that because we expected that, but just because it came out that way, it doesn't mean it's what it is."
Earlier this year members of the United Christian Leadership Ministry called for an independent investigation in this case.
Davis was a decorated Marine Corps veteran who the D.A.'s office says struggled with PTSD and addiction
