"The people that are paid to protect and serve are the same ones that took her life," said James Sharpe.
Sharpe lost his 19-year-old daughter Breanne Sharpe after she was killed by police fire in 2016; it was after she drove a stolen car toward officers after in a high-speed car chase.
Sharpe is now a part of the "Justice for Desmond Campaign" which is fighting for change in Butte County policing, centering around the officer-involved shooting deaths of a dozen people with known mental illnesses.
25-year-old Chico man Desmond Phillips was among them, killed by Chico Police after his father called them in distress.
Now, the Phillips family is taking their claims against local law enforcement to the state Attorney General.
"He will be overseeing this case personally, we have evidence that show that officers Gagnebin and Fliehr were not the only ones firing the guns at my son," said David Phillips on Monday morning.
The group alleges that there was at least one additional shooter aside from the two acknowledged in the D.A.'s report, who fired at Desmond the night he was killed.
They're also calling the Butte County District Attorney into question, and asking the state to look at a long list of incidents where police were found justified in altercations that ended in a shooting death.
"Four months after desmond was killed Alex Fliehr and Jeremy Gagnebin were involved in the killing of Tyler Rushing. We want all of these families to get justice," said Phillips.
"Tyler Scott Rushing was shot and killed by a private security guard a a Chico peace officer on July 23rd ... just a few weeks after Desmond was killed in an Officer-Involved Shooting. Paula and I have a private investigation right now ... we support Desmond and we love David Phillips," said Scott Rushing, Tyler Rushing's father.
Ramsey says that unfortunately, sometimes people with a mental illness attack officers ... those officers are not required to be injured or killed because of a persons mental health issues.
He says back in July, his office sent all of their reports to the Attorney General, who will do an independent review of the evidence that has already been gathered, with forensic reports done by the Department of Justice.
Ramsey says this is not an new, independent investigation.
