21-month-old Aiden Carter Doi fell three stories out of a window. His family tells KITV4 that he was leaning against a screen when it gave way.

The fall occurred from a unit at Hibiscus Hill Apartments on Ka Uka Boulevard in Waipi'o. 

As the family grieves, his aunt tells KITV4 he was a happy baby who loved to sing and dance. 

Aiden had two siblings, a 7-year-old brother and a 14-year-old sister. 

"They loved their little brother, always with him all the time, they do everything together. That's why it's so hard that this tragedy happened. They're really taking it hard too," aunt of Aiden, Corinna Doi, said. "We're trying to take it day by day, it's really hard to accept that he's really not here anymore."

Honolulu Police have opened an unattended death investigation.
