got second hand ipad has activation lock on it the owner moved cant find them help

If you’re not the original owner, the iPad is useless to you.

Here are the Apple support pages that outline the Activation Lock - and the only mechanisms by which it can be turned off:

Activation Lock for iPhone, iPad, and iPod touch - Apple Support

Turn off Activation Lock – Apple Support

As you will discover, unless you are the owner of the AppleID that was last used to activate the device, or unless you can secure the cooperation of the previous owner, you’ll not be able to defeat or bypass the Activation Lock. Without documentary evidence that you are the original owner (such as sales receipt showing the serial number), Apple won’t assist - and nobody here will be able to help you.

Return for refund if you can, or recycle it:

Activation Lock is a theft deterrent, and nobody—other than the person holding the credentials to the Apple ID holding the lock, or Apple and then only given the appropriate paperwork—can release the lock. And you don't have the appropriate paperwork.
