**WASHINGTON**
Fingerprints recovered from the scene of UnitedHealthcare CEO Brian Thompson's killing match those of Luigi Mangione, according to multiple reports published Wednesday.
Two anonymous law enforcement officials told CNN about the match amid the ongoing investigation. It is the first time Mangione has been forensically linked to last week's assassination outside the Hilton in Midtown Manhattan.
ABC News reported that the fingerprints were recovered from a used water bottle and a mobile phone.
Mangione remains in police custody in the state of Pennsylvania where he was apprehended following a days-long manhunt. He is seeking to fight his extradition to New York where authorities have charged him with second-degree murder.
Mangione, 26, was recognized by an employee at a McDonald's in Altoona, Pennsylvania, about 300 miles (482 kilometers) west of Manhattan, where Brian Thompson's murder happened last Wednesday. The restaurant worker called local police who responded to question the suspect.
Investigators say Mangione was acting suspiciously, and said when they stopped him, officers found him carrying a 3D-printed ghost gun with a sound suppressor in addition to multiple fake IDs and a US passport.
"We believe at this point ... our investigation is leaning toward he was acting alone,” New York City police department chief of detectives Joseph Kenny told reporters.
Officials said Mangione was also in possession of a document blasting the US health care industry. A review written by Mangione was also found online where he shared his thoughts.
"These companies don't care about you, your kids, or your grandkids," Mangione wrote on his GoodReads online account. "They have zero qualms about burning down the planet for a buck, so why should we have any qualms about burning them down to survive?"
