2 requests in onClick

Question

I have an onClick in an image with 2 requests:

1) a check 2) a redirect

function verifica(Msg) {
 return confirm(Msg);
}

And the image:

 <img 
     src="'.$imagemExclui.'"
     align="center" 
     style="height: 40px;" 
     title="Excluir Produto"
     onClick="return verifica(\''.$mensagem.'\');
                     document.location=\'?acao=remove&indice='.$produto["idProdutos"].'\'"; />

But when I call the function checks, if I withdraw the return it works, but even if I select yes, it does not follow, if I leave and return, it doesn’t work.

What to do?
