Reports indicate that the UnitedHealthcare CEO shooting suspect did not flee New York via bus, as previously thought, but rather by train.

Reports indicate that the suspect accused of murdering UnitedHealthcare CEO Brian Thompson in New York City earlier this month did not escape via bus, but rather via train.

On the morning of Dec. 4, in Midtown Manhattan, Luigi Mangione was accused of murder after he is said to have shot Thompson while Thompson was entering the Hilton.

Five days after the shooting, Mangione, 26, was caught in Altoona, Pennsylvania.

Initially, investigators believed Mangione had taken a bus out of the city based on surveillance footage at the George Washington Bridge bus station. However, they now suspect he took the subway from the bus station to Penn Station and purchased a train ticket to Pennsylvania before being apprehended, according to CBS News and ABC News, citing police sources.

In Pennsylvania, Mangione is being detained in a prison, pending extradition to New York.

He was denied bail Tuesday.

In Altoona, at a McDonald's, authorities apprehended Mangione, who allegedly presented police with a fake ID and seemed to tremble when asked about recent activity in New York.

A handwritten manifesto criticizing the health care industry, including UnitedHealthcare, was discovered by officials, as previously stated by NYPD Chief of Detectives Joseph Kenny to Planet Chronicle.

In New York, Mangione is charged with 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.

According to court documents, he is charged with 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 in Pennsylvania.

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

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