NEW YORK (AP) — A man with a gun thought to be similar to the one used in the killing of UnitedHealthcare CEO Brian Thompson was taken into police custody Monday for questioning in Pennsylvania, a law enforcement official told The Associated Press.
The man is being held in the area of Altoona, Pennsylvania, about 233 miles (375 kilometers) west of New York City, the official said. The official was not authorized to discuss details of the ongoing investigation and spoke to the AP on condition of anonymity.
Thompson, 50, was killed last Wednesday in what police said was a “brazen, targeted” attack as he walked alone to the Hilton from a nearby hotel, where UnitedHealthcare’s parent company, UnitedHealth Group, was holding its annual investor conference, police said.
The shooter appeared to be “lying in wait for several minutes” before approaching the executive from behind and opening fire, NYPD Commissioner Jessica Tisch said. He used a 9 mm pistol that police said resembled the guns farmers use to put down animals without causing a loud noise.
Ammunition found near Thompson’s body bore the words “delay,” “deny” and “depose,” mimicking a phrase used by insurance industry critics.
Monday’s development came as dogs and divers returned to New York’s Central Park while the dragnet for Thompson’s killer stretched into a sixth day.
Investigators have been combing the park since the Wednesday shooting and have been searching at least one of its ponds for three days, looking for evidence that may have been thrown into it.
On Friday, police found a backpack in the park that they say the killer discarded as he fled from the crime scene outside the New York Hilton Midtown in Manhattan to an uptown bus station, where they suspect he left the city on a bus.
But they had not yet found the gun or the shooter, nor had they identified him by name.
On Monday, K-9 units sniffed leaf-covered planters between walking paths in Central Park near where police found the shooter’s backpack. Farther along the path that police suspect he took through the park after the shooting, scuba divers geared up and started searching a pond for the third straight day.
Retracing the gunman’s steps using surveillance video, investigators say the shooter fled into Central Park on a bicycle at 60th Street and Center Drive, emerged from park without his backpack at 77th Street and Central Park West and then ditched the bicycle about 7 a.m. near 85th Street.
He then walked a couple blocks and got into a taxi, arriving at 7:30 a.m. at the George Washington Bridge Bus Station, which is near the northern tip of Manhattan and offers commuter service to New Jersey and Greyhound routes to Philadelphia, Boston and Washington, NYPD Chief of Detectives Joseph Kenny said.
