The 26-year-old man is suspected of weapons offenses. New York's Mayor Eric Adams says that the man has several items in his possession that are believed to "link him" to the shooting, reports NBC News.
At this point, we believe – our investigation suggests – that he acted alone, says high-ranking New York police officer Joseph Kenny according to CNN.
The CEO of the American insurance company United Healthcare, Brian Thompson, was shot multiple times early on Wednesday morning outside a hotel on Manhattan.
Kenny says that a handwritten document has been found, suggesting that the suspected man harbors ill will towards the dominance of large corporations in the USA.
Corrected: In an earlier version, the wrong day was stated for the murder.
