High school photos of Las Vegas mass murderer Stephen Paddock have emerged, showing him as a geeky teen back in the 1970s.

Paddock clutches a tennis racket and poses in one picture with his school varsity tennis team, and smirks for the camera in his yearbook picture.

He graduated from John H. Francis Polytechnic High School in Sun Valley, California, in 1971.

Forty-six years later, he went on to murder 59 people and injured more than 500 after opening fire on a crowd of concertgoers from a 32nd-floor window at the Mandalay Bay in Las Vegas.
