Luigi Mangione’s appearance in court in Pennsylvania today begins a series of hearings in two states on a series of criminal charges related to the murder of UnitedHealthcare CEO Brian Thompson.

Here’s what Mangione expects in court:

Pennsylvania State Fees: Mangione faces firearms charges in connection with the 3D-printed gun and false IDs that police say were found in his possession when he was arrested at McDonald’s. Blair County District Attorney Peter Weeks said he would not push for those charges to be tried ahead of Mangione’s much more serious charges in New York.

Extradition from Pennsylvania: Mangione has the right to challenge the arrest warrant issued in New York requiring his appearance in connection with the murder. His attorney says Mangione is waiving that right and he is expected to be transported to New York once the hearing is over.

New York State Charges: Manhattan District Attorney Alvin Bragg has filed first- and second-degree murder charges and three other charges against Mangione in connection with Thompson’s death. The first-degree murder charge was added based on allegations that Thompson’s killing was not just directed at the victim but was an act of terrorism.

The timing of Mangione’s first court appearance in New York has not yet been confirmed, but CNN senior legal analyst Elie Honig said it will likely be no later than Friday. Now that Mangione has hired prominent New York attorney Karen Friedman Agnifilo, Honig doesn’t expect any more dramatic scenes than before his first hearing in Pennsylvania.

“I promise you, Karen Friedman Agnifilo came to him and said, ‘Shut up. No more breakouts. “None of that stuff you did the other day,” Honig said.

It is very unlikely that Mangione will be granted bail, said CNN senior law enforcement analyst Andrew McCabe. “In the end, he will remain at Rikers Island along with all the other inmates in New York City awaiting some kind of trial or trial,” McCabe said.

Possible federal case: In addition to the murder charges filed in state court, Mangione is also expected to face federal charges in the case, sources tell CNN’s Kara Scannell.

“The federal government’s reported decision to pursue an already inflated first-degree murder and state terrorism case is highly unusual and raises serious constitutional and statutory double jeopardy concerns,” Agnifilo said in a statement.

The likelihood of a federal prosecution only adds to the spectacle of the case, since the state and federal courthouses are directly across from each other in Manhattan. “Both murder trials could run more or less parallel to each other,” Honig said.
