One person was shot during a deadly shooting outside the office of a law firm in Litchfield, state police say.

The shooting happened Monday in the parking lot of the Cramer & Anderson Law Office on West Street in Litchfield around 5 p.m.

The State Police Major Crime Squad was called in after a report of a disturbance and a gun being fired.

Law enforcement officials say they found 39-year-old Matthew Bromley suffering from a gunshot wound. He died of his injuries.

State Police say they identified the shooter, and a gun was recovered at the scene.

They say the shooting involved at least one person associated with the law firm.

State Police say the shooter was permitted to carry the gun and that he called 911 following the incident.

Police say the man accused in the shooting was not placed under arrest, but that he is cooperating with the investigation.

The motive behind the shooting is still unclear.

Cramer & Anderson released a statement on the incident saying, "A tragic incident occurred at the Litchfield office of Cramer & Anderson LLP Monday involving Partner Robert Fisher. State Police have labeled it an isolated incident and said there is no danger to the community. Attorney Fisher will be on a leave of absence while the police investigation is carried out, and our Litchfield and Washington Depot offices will be closed Tuesday. The firm is fully cooperating with investigators. Inquiries should be directed to Partner Ken Taylor of the firm’s main office in New Milford."

Police are trying to figure out the exact relationship between the shooter and the victim. 

"The relationship between the shooter and the deceased are unknown. We do believe they know one another, but in terms of the exact relationship of both parties is unknown at this time," Connecticut State Trooper Josue Dorelus says.

Detectives are working to identify witnesses and see if there's surveillance video in the area.

They are asking anyone with information to come forward.

State Police say the incident was an isolated one and that there's no threat to the public at this time.
