In Rodriguez v. McDonald, --- F.3d ---, No. 12-56594 (9th Cir. 2017), the Court grants habeas relief in a case where "a boy who invoked his
constitutional right to the assistance of counsel was denied
this assistance, and then was badgered into confessing
murder."
There is lots of good language about reinitiating after an invocation. If you have a case where your client invoked before ultimately confessing, this decision is helpful.
