Reports say the suspect in the UnitedHealthcare CEO shooting escaped New York by train, not by bus as initially believed.

The suspect accused of murdering UnitedHealthcare CEO Brian Thompson earlier this month in New York City fled Manhattan via train and not by bus as originally thought, according to reports. 

Luigi Mangione was charged with murder after he allegedly shot Thompson the morning of Dec. 4 as Thompson was walking into the Hilton in Midtown Manhattan. 

After the shooting, Mangione, 26, was on the run and was caught five days later in Altoona, Pennsylvania. 

In New York, Mangione faces one count of murder, two counts of second-degree criminal weapons possession, one count of second-degree possession of a forged document and one count of third-degree criminal weapons possession.

In Pennsylvania, he faces one count of forgery, one count of carrying a gun without a license, one count of tampering with records or identification, one count of possession of instruments of a crime and one count of presenting false ID to law enforcement, according to court documents.

While officials have not commented on an official motive, the public has speculated that the suspect had strong grievances with both the health care industry and capitalism in general.

UnitedHealthcare revealed Thursday to employees that Mangione was not covered by UnitedHealthcare.
