ANTIOCH, Calif. -- Antioch Police Wednesday were searching for a chiropractor who is suspected of drugging and sexually assaulting a female victim and then showing photos of the attack on his cell phone.

Authorities said they were searching for Jason Phillip Goettsch, 37, in relation to an incident that took place on Feb. 22. \ According to investigators, an officer saw Goettsch and another man dragging a woman into a car at Antioch's Hold Cardroom and Bar. The officer approached and asked if he could be of assistance, calling an ambulance for the woman.
