Authorities say they believe a BASE jumper overtaken by waves after leaping from a bridge overlooking the Pacific and the man who went in after her have drowned.

KION-TV in Salinas, California, reports (http://bit.ly/1PPe9a4 ) that the two have been missing since Saturday morning.

Monterey County Sheriff's officials say a video from a helmet camera shows Mary Katherine "Katie" Connell, of Ventura, descending 300 feet and landing on Bixby Creek as it feeds into the Pacific. Shortly after the landing, large waves overtake her.

Sheriff Steve Bernal says her companion then jumped off the bridge to help her.

Bernal says the man likely took off his helmet and parachute to rescue her and that's where the footage ends.
