A hearing in Luigi Mangione ’s state murder case in the killing UnitedHealthcare CEO Brian Thompson was postponed until Wednesday after prosecutors failed to inform his jailors that he was needed in court.

Judge Gregory Carro had scheduled the hearing for Tuesday but adjourned it about a half-hour after it was supposed to start when Assistant District Attorney Joel Seidemann told him that prosecutors had failed to send required paperwork to the jail.

“It’s on us,” Seidemann said. “We got the writ signed but we failed to serve it.”

“That’s unfortunate,” Carro replied.

Seidemann noted that the judge in Mangione’s federal case, Margaret Garnett, had sent an order to the jail authorizing him to wear a suit to court, but the prosecutor acknowledged that alone wasn’t enough to get him brought to court.
