The family of a man shot dead by U-S air marshals in Florida last week is still waiting for an explanation from U-S authorities.
The body of Rigoberto Alpizar has been buried in his native Costa Rica where funeral services were held in a town outside the capital.
U-S federal officials say Alpizar made a bomb threat in the jetway at the Miami International Airport after running frantically out of a plane. They said they opened fire because Alpizar ignored their orders to stop, instead reaching into his backpack.
No bomb was found. Witnesses said his wife frantically shouted amid the chaos that he was bipolar, and hadn't taken his medication.
His family in Costa Rica says they didn't know he suffered from any mental illness.
Rigoberto Alpizar left Costa Rica for the United States two decades ago. He became a naturalized U-S citizen and worked for the U-S hardware chain Home Depot, living in the Orlando suburb of Maitland.
