"Hsieh was locked inside a storage area at the back of the home and they were unable to get him out."

"A Broadcastify audio recording of the exchange between the city's emergency dispatchers, firefighters and police reveal that initial reports from the scene were of a fire and a man who had either barricaded himself inside or was trapped in the waterfront home. Firefighters arrived at the home to find individuals outside and Hsieh still inside. Police were called in to assist.

The dispatcher reported to firefighters that the man still inside was in an outbuilding attached to the main part of the home, “and the male is barricaded … he’s not opening the door. Everyone else is outside the house. They’re trying to get him to open up.”

While the dispatcher repeatedly said "barricaded," city police on Monday, in an updated press statement, said first responders learned from people at the scene that Hsieh was locked inside a storage area at the back of the home and they were unable to get him out. Dark smoke was observed coming from the storage area."
