The family of Joshua Wayne Harvey, a man who died after being tasered by three police officers a total of 27 times in three minutes, is demanding a criminal investigation.
On August 24, Tulsa police say Harvey, 25, was acting strangely downtown and removing his clothing.
Body cam footage shows officers pursuing Harvey, following him into a bank where he allegedly broke a door with his head before officers began tasering him.
Harvey, who had history of struggling with mental illness, died three days later on August 27.
Damario Solomon-Simmons, the family's attorney, says his clients aren't satisfied with the investigation into Harvey's death.
"They did not do their jobs," Solomon-Simmons said
"They broke the laws when they excessively, unnecessarily and illegal tased him 27 times in a period of approximately two minutes."
The Tulsa Police Department's use-of-force report found no wrong doing.
None of the officers seen in the video have been charged with any crimes.
