One man is dead after an incident involving two shooters and a Seminole County Sheriff's Office deputy early Saturday morning. 

The sheriff's office said its deputy found himself in the middle of a "rapidly evolving situation involving gunfire" at a block party and shot at an armed subject, hitting him. 

The subject was pronounced dead at the hospital. The deputy's deadly use of force is being investigated by the Florida Department of Law Enforcement.

Deputies with the Seminole County Sheriff's Office responded to the 2200 block of Sipes Avenue in the Midway community of Sanford, around 1 a.m., June 20 in response to a noise disturbance. When on the scene, deputies encountered a large block party and tried to disperse the crowd, the sheriff's office said. 

According to the sheriff's office, early information indicates that two shooters were involved in the incident, in which a sheriff's deputy "found himself in the middle of an active and rapidly evolving situation involving gunfire in a large crowd," SCSO said. 

An armed subject began shooting, which led to the deputy engaging the armed subject and shooting him, the sheriff's office said.
