South Carolina authorities continue to search for the suspect or suspects who carried out a mass shooting that left 11 people injured on Sunday evening in North Myrtle Beach.

The Horry County Police Department described the shooting as an isolated incident stemming from an altercation on a charter boat during a private Memorial Day gathering. 

A total of 10 victims sustained gunshot wounds and another person reported an unknown injury not related to gunfire, the police department said in a Monday press release. Some victims were recovered from the water, the North Myrtle Beach Police Department (NMBPD) said.

“Of those, the worst of the injured are in critical but stable condition at area hospitals,” Horry County police said in a press release.

Video footage obtained from a witness apparently shows the incident, and authorities determined that “the discharge was from the wounded Officer’s rifle,” and the scene was released to SLED.

Horry County police said the shooting remains under investigation, and “there is currently no associated risk to the community.”

Crime concerns in and around Myrtle Beach have been heightened since April 26, when a shooting in the Myrtle Beach entertainment district left the shooter dead and 11 victims injured. Myrtle Beach officials described the shooting as an isolated incident at the time.
