MIAMI -- Authorities said a man who was found dead on a roof near a beehive Tuesday died of natural causes.

Jorge Acosta, 61, was found dead near a hive of angry bees on the roof of the Tree Top apartments in the 10800 block of Southwest 84th Street.

Miami-Dade police said Wednesday that Acosta was a freelance bee expert who agreed to remove the bees from the roof. Police said he planned to take the bees to his home, where he cultivates beehives.

Authorities said Acosta was wearing the top half of a protective bee suit. Initially, investigators said they were not sure whether Acosta fell, had a heart attack or was killed by a swarm of bees.

"It's hard to say. We're going to let the medical examiner's office dictate whether he was stung by bees or not. We didn't find any obvious bee stings on the gentleman," Chief Al Cruz of Miami-Dade Venom Response said Tuesday.

The medical examiner's report found that Acosta died of natural causes, according to Miami-Dade police.

Private beekeeper Rolando Calzadilla removed the 80-pound hive from the soffit of the building and estimated there were about 20,000 bees there. But, Calzadilla said, there was nothing to indicate that the insects were deadly Africanized honeybees.

"By the time we got here, they were already agitated, so they were no more aggressive than any other bee defending their hive at that point," Calzadilla said.

Local 10 learned that residents of the apartments have been buzzing about bees on the property for months.

"Those bees have been there about six months," said resident Jorge Toledo.

Resident Albert Alonso showed Local 10's Roger Lohse two more beehives on other buildings in the complex. He said he and his neighbors have pleaded with management to call the beekeeper.

"We complained about a month ago, and they said they were going to get rid of them," Alonso said.

Local 10's Roger Lohse asked the woman in the rental office if that was true, and while she confirmed she knew the building had a bee problem, she didn’t want to discuss the why the hive was not removed.

"Why wasn’t this taken care of sooner? " Lohse asked.

"I have no more comments to make," the woman replied before escorting Local 10's cameras out of the building.

A DNA sample of the insects will be tested to determine exactly what kind of bees they are.
