The FBI is now offering a reward of up to $50,000 for information related to the murder of UnitedHealthcare CEO Brian Thompson.
A manhunt for the suspect has expanded across multiple states, as authorities believe the individual may have used a fake ID from New Jersey to book a hostel room before the shooting.
Investigators also think the suspect may have arrived on a bike, before boarding a busfrom Atlanta to New York.
Authorities are analyzing a water bottle and a cell phone found at the scene for DNA evidence, along with bullets collected earlier, while the backpack found in Central Park late Friday suspected to be linked to the crime, has been sent for forensic analysis.
