From NPR.

Luigi Mangione, the man accused of killing UnitedHealthcare CEO Brian Thompson, will be back in a New York state courtroom today as his lawyers attempt to get some of the evidence in his case thrown out.

The defense has asked the court to suppress all evidence recovered from Mangione’s backpack — including a written-in notebook, a 9 mm handgun and a silencer — because they say it was unlawfully searched without a warrant. They also want statements Mangione made to law enforcement — before he was read his Miranda rights — to be suppressed, as well.

Mangione also faces a federal trial. If he’s found guilty in that case, he could face the death penalty.
