Dec. 4 (UPI) -- A police officer who questioned Luigi Mangione in an Altoona, Pa., McDonalds testified in court Thursday in a pre-trial evidentiary hearing.

The testimony came on the third day of the hearing in which Mangione's lawyers are trying to have evidence gained by police without a warrant suppressed. It's also the one-year anniversary of the shooting of UnitedHealth Group CEO Brian Thompson, 50, for which Mangione is charged.

Mangione, 27, is accused of fatally shooting Thompson on a sidewalk in Manhattan. He was captured five days later in the Pennsylvania McDonalds.

Mangione and his lawyers are in court to get his first statements, his notebook and a gun found in his backpack excluded from evidence at trial because police seized them before they had a search warrant.
