Dec. 1 (UPI) -- The death of retired Zappos CEO Tony Hsieh last week that was linked to a Connecticut house fire has been ruled an accident.
Hsieh was visiting family in Connecticut at the time of the fire, officials said.
New London Police Capt. Brian Wright said Hsieh was "locked inside a storage area" at the home and could not escape.
The medical examiner said Hsieh died from complications related to smoke inhalation. The official investigation into the fire's cause has not yet been completed.
Megan Fazio, a spokeswoman with Hsieh's Las Vegas-based DTP Companies, said he'd been visiting Connecticut with his brother. A Zappos employee owned the home where the fire occurred.
New London Fire Chief Thomas Curcio said the cause of the fire is still unknown.
Hsieh joined ShoeSite.com, which later became Zappos, in 1999 and oversaw the company through its purchase by Amazon in 2009 for $1.2 billion. He retired in August.
