A man was pronounced dead Monday night at Tampa International Airport after a series of events that started with him saying he was watching planes and ended with him leaping off the parking garage, according to officials.

In between, an airport police officer fired shots at the man, who was identified Tuesday morning as 46-year-old Allen Piano.

The incident that began at 4:30 p.m. Monday when an airport officer approached Piano on the eighth floor of the short term parking garage. He told the officer he was watching planes, authorities said.

Police said the officer ran a background check, which revealed Piano was a sex offender who was about to have a warrant issued for his arrest. The man's probation officer told airport police a shotgun was also missing from the home of Piano's parents, with whom he lived.

A half hour later, police say, the officer found Piano on the fourth floor of the long-term parking garage, sitting in his car with a gun in his mouth.

Police said the officer ordered Piano to put the gun down. The man exited his car and lunged at the officer, according to police.

The officer discharged his gun. Police said Piano then turned and jumped from the parking garage.

According to the Medical Examiner, Piano was shot multiple times.

The officer involved is on routine administrative leave pending the results of the investigation.
