James Capers v. United States

In regards to 21 U.S.C. §846, to be in accordance with both Apprendi and Alleyne , to punish as 21 U.S.C. §841(b)(1)(A) (10 to life), must the jury find both the conspiracy amount (Apprendi) and the amount the defendant was personally responsible for (Alleyne), i.e. must two questions be answered?

In regards to 18 U.S.C. §1962(d), to be in accordance with Apprendi to punish beyond the statutory maximum of 20 years, where the jury instructions cited first and second degree murder, attempted murder, conspiracy to murder, and gave Pinkerton instructions, all under New York State Law, to take'<the statutory maximum to life, does the jury have to find more than that the underlying offense "involved [] murder"?

When these questions are brought up pro se for the first time on appeal after a remand for resentencing, where the issues were as above, is Capers properly challenging his sentence, or are these Constitutional challenges not properly brought on remand?
