'Tens of thousands of hours of footage': How cops plan to hunt down Brian Thompson's killer

New York City's vast surveillance network has become the foundation of the investigation into the fatal shooting of UnitedHealthcare's CEO Brian Thompson, on a busy Manhattan street Wednesday morning.
The New York Police Department (NYPD) collecting the trails of digital evidence from public and private cameras to track the gunman, whose calm appearance and precision have raised alarms about his proficiency with firearms.
According to The New York Times, the shooting took place just before 7am on West 54th Street. Surveillance footage showed the suspect, dressed in black with a gray backpack, loitering for several minutes before locking onto his target.
The gunman approached Thompson, raised his weapon, and fired several times. A nearby woman ran for cover as Thompson collapsed to the ground.
Police chief of detectives Joseph Kenny described the suspect as methodical and skilled, while Commissioner Jessica Tisch confirmed that the man disappeared into Central Park on a bicycle after the attack. Despite extensive footage, no arrests have been made, and neither the suspect’s identity nor the motive has been determined.

The NYPD, using its advanced surveillance capabilities developed post-9/11, is deploying aviation units, drones, and K-9 teams in its search. Officers are also combing through social media, interviewing Thompson's associates, and analysing footage from Midtown Manhattan.
"An incident like this happens, we don’t spare any expense," said chief of department Jeffrey Maddrey.
The shooter’s movements before and after the crime were extensively captured. Cameras in a Starbucks two blocks from the scene recorded his partially obscured face minutes before the shooting. Footage then showed him fleeing through a pedestrian passage near the Ziegfeld Ballroom, where police later found a cellphone.

While NYC's surveillance network is among the most expansive in the nation, its effectiveness hinges on human expertise. Brittney Blair, a senior director at K2 Integrity and a former intelligence operations leader, told The New York Times that investigations of this nature are “extremely tedious,” requiring meticulous analysis of thousands of hours of footage. Despite the technology, she mentioned, public tips remain crucial.
The challenges of harnessing surveillance were evident in the April 2022 Brooklyn subway shooting, where it took police 31 hours to apprehend the suspect, Frank James, despite clear video evidence. That case underscored the need for both investigative skill and public involvement in identifying suspects.
Blair also pointed out that Manhattan, with its dense network of cameras, is perhaps the worst place in the country for a criminal to commit such a crime. “There is no magic button you can press to immediately identify someone,” she said. "But of all the places in this country to commit a crime like this, Manhattan would be the dead last location on my list."
As police continue to review footage and gather evidence, the public remains a crucial ally to help identify the suspect in a high-profile and chilling case.
