U.S. authorities have arrested a man in Altoona, Pennsylvania, in relation to the murder of UnitedHealthcare CEO Brian Thompson, who was killed in New York last week. The suspect was found with a firearm, silencer, and fake identification linked to the crime. Thompson was shot outside a Manhattan hotel by a masked assailant who then escaped by bike and taxi. Investigators are examining the suspect’s ties to the murder as they continue their search for the perpetrator.
