New York police released photos Thursday of a person wanted for questioning in connection with the fatal shooting of UnitedHealthcare CEO Brian Thompson.

The two photos show most of the face of the person the NYPD is searching for in connection with its investigation into Wednesday’s murder in midtown Manhattan.

Thompson, 50, was killed by a masked gunman early Wednesday morning as he made his way to the entrance of the Hilton Hotel for an investor meeting UnitedHealth Groupthe parent company of UnitedHealthcare.

UnitedHealthcare is the largest private payer of health insurance services in the United States.

“The New York City Police Department is requesting the public’s assistance in identifying the individual depicted in the newly attached media to be interviewed in connection with the murder listed below,” the NYPD’s Media Affairs Office said in a statement.

The NYPD and Crime Stoppers have offered a $10,000 reward for information leading to the arrest and conviction of the person responsible for killing Thompson.
