Q: what should i do if i cant contact the previous owner

Where did you purchase the device? Can you return it for a refund? If you cannot contact the previous owner, there is nothing that can be done. The device is activation locked and is useless to you, or anyone else until the previous owner removes the activation lock.

Can someone return It to apple and they can return to the original owner?

Apple will not get involved in returning a device.

No, Apple doesn't get involved in lost iDevice matters.

You should turn a iDevice you find into the nearest police station.
