The family of Caldwell man Anthony Firkins Jr., 33, wants to conduct a private query to find out what happened, according to his sister.
Firkins died in April shortly after Nampa police arrested him following a car and foot chase. He stopped breathing and was pronounced dead at a local hospital.
Brandy Firkins of Kent, Wash., said her family was "devastated" by the loss.
"He was a great brother, and a great son," she said.
The public investigation into Firkins' death is not complete. The Critical Incident Task Force, led by the Canyon County Sheriff's Office, is reviewing the incident.
Firkins' autopsy results and toxicology report also are not yet available, according to the Canyon County coroner. His sister said she has not received anyinformation from the Nampa Police Department or the Canyon County Sheriff's Office about the cause of death.
Brandy Firkins said she is not aware of any heart conditions or underlying medical problems that might have contributed to her brother's death.
She also said she does not blame police. She's waiting for the investigation to be wrapped up instead of jumping to conclusions.
"It's not my place to put judgment on anybody, and I won't," she said.
Nampa officers were responding April 19 to a report of "suspicious circumstances" when they said they saw Anthony Firkins' pickup being operated recklessly, with no lights on.
After several minutes of pursuit, Firkins lost control and crashed near 11th Avenue North and Industrial Road, according to a police news release in April.
Firkins got out of the pickup and jumped a fence, police said. Officers found him hiding under a trailer and took him into custody.
Soon after that, he simply stopped breathing, police said.
Firkins had a handful of prior convictions, including for assaulting a correctional officer in 2007 in Cassia County.
