A 48-year-old Hamilton County Jail inmate died in October from natural causes, according to a medical examiner's report.
An autopsy performed on Phillip Dale Ellis showed no signs of trauma or foul play, according to the report, released Tuesday afternoon.
Ellis died from bronchopneumonia, according to the report, which also states that he had a heart condition that contributed to his death.
The toxicology report showed Ellis was on prescription medication at the time.
Ellis, who was found alone and unresponsive in his jail cell on Oct. 6, had bruises and abrasions to his feet and legs, according to the report.
Despite the release of the report, his family still has many unanswered questions, said Joy Carr, Ellis' sister. She said the family has hired an attorney.
Staff were able to resuscitate Ellis, but he died hours later at Erlanger hospital.
Ellis was jailed after he reportedly pulled a gun on a Republic Parking employee on Sept. 18.
Hamilton County Sheriff's Office SWAT team members arrested him a couple of days later at his home and executed a search warrant, where they confiscated more than a dozen marijuana plants along with equipment to cultivate the plants, authorities said.
