McNabb struggled with officers before they were able to handcuff him. They believed McNabb was overdosing and called EMS. As officers spoke with McNabb, he began to calm down but was breathing heavily and sweating profusely, police reported.

As the officers waited for EMS, McNabb stopped breathing. Officers could not detect a pulse.

Crestview firefighters arrived and began CPR before EMS took McNabb to North Okaloosa Medical Center. He was pronounced dead shortly after his arrival.

The Florida Department of Law Enforcement will investigate McNabb’s death because he died in police custody, the release said.

The responding officers have been placed on modified duty pending a debriefing.
