AUSTIN, Tex. — The wood coffin that held the body of Lee Harvey Oswald belongs to his brother and not a Fort Worth funeral home that sought to sell it for more than $87,000, a Texas judge ruled Friday.

Judge Donald J. Cosby of District Court in Fort Worth found that the Baumgardner Funeral Home and its owner, Allen S. Baumgardner Sr., had engaged in “wrongful and wanton and malicious conduct” by concealing the existence of the coffin from Oswald’s older brother, Robert, and by putting it up for sale years later through a Los Angeles auction house.

Robert Oswald, of Wichita Falls, Tex., sued to reclaim the coffin after learning that the Nate D. Sanders auction house had sold it to an undisclosed bidder on the funeral home’s behalf for $87,468. The 2010 sale was halted after Mr. Oswald filed suit, and the coffin has remained in storage at the auction house.

The coffin was the one Lee Harvey Oswald was buried in after killing President John F. Kennedy on Nov. 22, 1963. The body was exhumed in 1981 to dispel conspiracy rumors that a Soviet agent had been buried instead of Oswald. The coffin had deteriorated so badly that Oswald was reburied in a new coffin and the original was taken to the Fort Worth funeral home.
