Former football star O.J. Simpson's foreclosed South Florida house was sold for $655,000 in an online auction this week, media reports said.

The four-bedroom and four-bath house in Miami's Kendall section was sold at auction on Tuesday, but the buyer's name has not been revealed.

The 65-year-old Simpson, who has served four years in a Nevada prison out of a sentence of nine to 33 years for a 2007 conviction for kidnapping and robbery, lost the house in foreclosure to JP Morgan Chase, the Business Journal reported.

The judge handling the case "ruled the $660,982 in principal on the mortgage had not been paid since March 2010. Four years of taxes were owed as well," the Business Journal said.

Simpson bought the house, which was built in 1953, for $575,000 in 2000, five years after a California jury acquitted him of the 1994 murders of his ex-wife, Nicole Brown Simpson, and her friend, Ronald Goldman.

The former NFL star lost a civil judgment in 1997 for their wrongful deaths and was ordered to pay the victims' families $33.5 million. EFE
