Three days after 63-year-old Floyd Jackson died in the Coconino County jail, the Coconino County Medical Examiner announced the preliminary cause of death.
Complications of peptic ulcer disease with other significant underlying conditions caused Jackson to die Sunday morning, according to the medical examiner. Questions regarding the details leading to Jackson's death were asked to Coconino County jail commander Matthew Figueroa on Monday prior to a county press release on Wednesday afternoon.
Jackson had been transported from Maricopa County jail to Coconino County jail on Sept. 12, and was being held on a $200 bond on a warrant for failing to comply for driving on a suspended license out of the Flagstaff Justice Court.
When booked into the jail, Jackson informed the staff he experienced multiple serious medical conditions, but did not include ulcers among them. After a medical assessment of Jackson’s condition was conducted on Friday, Sept. 13, jail staff ordered lab work to be completed and began to administer medications to Jackson for his condition. Jackson was housed in a cell by himself within the jail’s medical unit, and medical staff began to obtain medical records from his former health care providers.
Jackson told an officer he was having difficulty breathing around 12:40 a.m. on Sunday, Sept. 15, and a diagnostic test on him indicated an appropriate oxygen level in his blood. The officer then contacted the on-call nurse and informed them of Jackson’s complaint and test results.

The nurse told staff Jackson could remain in the jail and the morning-shift nurse would follow up. At 6:15 a.m. Sunday morning, the new nurse administered oxygen to Jackson, who said he was feeling better. However, during Jackson’s next assessment at 7:16 a.m., he became unresponsive.
Life-saving measures on Jackson were started and continued until paramedics arrived, but he died at 7:46 a.m.
This incident remains under investigation by the Coconino County Sheriff’s Office criminal investigations division and the Coconino County Medical Examiner. The sheriff's office added the information remains preliminary and may change as the investigation continues.
Jackson’s death is the second in the Coconino County jail this year after 20-year-old Kyle Martinson was found unresponsive in his cell in January. Martinson, whose oxygen level was also within the standard to remain in jail, was found to have died as a result of pneumonia caused by strep throat, and had almost 1.5 gallons of fluid putting pressure on his lungs.
