Buck Ruxton (born Bukhtyar Chompa Rustomji Ratanji Hakim; 21 March 1899 – 12 May 1936) was an Indian-born physician convicted and subsequently hanged for the September 1935 murders of his common-law wife, Isabella Ruxton (née Kerr), and the family housemaid, Mary Jane Rogerson, at his home in Lancaster, England. These murders are informally known as the Bodies Under the Bridge and the Jigsaw Murders, while Ruxton himself became known as The Savage Surgeon.
