Nearly 36 hours since Thompson was killed on a New York City sidewalk, investigators are still working to find the shooter.
The latest: The NYPD released new photos of a person of interest in the case.
They've lifted a fingerprint from a discarded water bottle and have a burner phone believed to have been dropped by the shooter, CNN reported.
And investigators carried out a warrant on a hostel on Manhattan's Upper West Side in connection with the investigation, according to multiple reports.
What they've found: Police say shell casings found at the scene of the murder were inscribed with words including "delay" and "deny" — "possible references to ways that health insurance companies seek to avoid paying patients' claims," NYT reported.
State of play: Police have reportedly not yet been able to match a name to the person in the photos.
