Investigators probe into the murder of UnitedHealthcare CEO, focusing on the family for possible motive.

The New York Police Department likely employed a multipronged strategy in their efforts to find the killer and his motive after the murder of UnitedHealthcare CEO Brian Thompson in Manhattan, according to former law enforcement officers.

On Wednesday at 6:46 a.m., a gunman in black clothing and a face mask aimed a silenced pistol at Thompson outside the Midtown Hilton Hotel and fired three shots.

The NYPD is investigating a murder and has found several clues, including a phone dropped in an alley, a water bottle left at a Starbucks, words on shell casings, and images of a person of interest at a hostel.

Numerous ex-law enforcement officials informed Planet Chronicle Digital that they were certain the assassin would be apprehended due to the evidence left behind.

"While law enforcement is in a reactive state about this, the public should have confidence in the NYPD's ability to solve the case. The NYPD has highly skilled investigators, cutting-edge technology, and the manpower to dedicate to the investigation," Matt Fagiana, a retired police sergeant and law enforcement consultant, told Planet Chronicle Digital.

"We've got multiple people looking at multiple angles at the same time," he said. "There are multiple, simultaneous missions going on as we speak."

Currently, the NYPD is searching for additional surveillance footage of the perpetrator to gather more clues, as stated by retired FBI Agent Scott Duffey.

The technology is designed to enable individuals to identify the location of a camera or security footage and retrieve the footage from the cloud or hardware, then return it to the police department.

Investigators in New York will examine video footage to determine the shooter's location before and after the incident at the Hilton.

Duffey eventually stated that with their video experts, surveillance teams, and facial recognition software, they would be able to identify the unmasked individual through a few possible hits, including a passport or driver's license photo.

Another aspect of the investigation will be conducted in Minnesota, according to Duffey.

Duffey advised starting with the inner circle in the investigation of a targeted murder on a public block in a large city. He emphasized that if the premise is that it's a targeted crime, then it's important to focus on the family situation of the victim. A victimology will be conducted on Thompson, involving interviews with his family, friends, and colleagues.

Duffey advised narrowing down the suspect pool by drawing a small circle and excluding them, before expanding the circle.

Pauline Thompson, the wife of CEO Thompson, who was previously living separately from him, stated that her husband was receiving death threats.

"Duffey inquired about the form of the communication, stating that many individuals in Thompson's position receive numerous threats, similar to political figures. However, it is not necessary to examine thousands of threats, as it may lead to a distraction."

"The type of communication, what is being said, and how it's being said are important factors to consider when determining if the threats are consistent with the incident. Law enforcement should quickly be able to determine if the message is similar to one that could have been sent from the same individual."

If the killer's fingerprints or DNA are already in the national CODIS system of arrestees, the forensic evidence from the scene could also play a crucial role in identifying him quickly.

If the case remains unsolved, a genealogical DNA profile could be established to identify the assassin through any kin who have utilized DNA ancestry services.

Alternatively, the public could help solve the case.

""Someone will recognize the facial features of this guy and say 'oh my gosh, that's my brother' upon seeing photos distributed by the agency," Duffey stated."

The NYPD is providing a $10,000 reward for information leading to the apprehension of the suspect in the case. The public is encouraged to contact the Crime Stoppers hotline at 1-800-577-TIPS (8477) or submit a tip through their website. All calls are kept confidential.
