One dead, 11 injured in US tourist town shooting

In a statement, the department said "based on the immediate threat" an officer then shot one person, who died from their injuries.

Myrtle Beach Mayor Brenda Bethune told WBTW-TV the officer responded appropriately. The Horry County deputy coroner identified the person shot as 18-year-old Jerrius Davis, according to WBTW.

"Our officer saw what happened, and when he saw that an altercation was taking place and a gun was being shot, the officer responded very quickly and in my opinion, saved lives," Horry County Deputy Coroner Tamara Willard said. 

"Last night could have been so much worse."

The department said 11 people who sustained injuries were receiving medical treatment.
