The respected doctor who will deliver Kate Middleton’s royal baby was once at the center of one of the U.K.’s most notorious unsolved murders.

Dr. Alan Farthing, who is overseeing the health of the Duchess of Cambridge through her pregnancy, was engaged to popular TV host and news anchor Jill Dando -- who has been dubbed the “British Katie Couric” -- when she was shot dead in broad daylight on the doorstep of her London home 13 years ago, the National Enquirer is reporting.

On April 26, 1999 Dando, 37, left her fiance’s house, went shopping, and returned to her own home where she was gunned down. The execution-like style of the shooting immediately prompted speculation that Dando might have been the victim of a professional hit man.

Farthing was questioned about the horrific crime and quickly cleared, but despite his iron-clad alibi, the physician couldn’t shake the incredible rumors that he may have had a hand in the murder. A Royal source told the Enquirer that the murder mystery still haunts Farthing, 47, who became Queen Elizabeth’s gynecologist in 2008.
