The men are considered persons of interest in the shooting, and Fort Myers police are investigating to determine if additional charges will be brought, Sergeant Matt McDaniel, a sheriff's spokesman, said in a telephone interview on Tuesday.

"At this time we have no updates regarding this active investigation," the Fort Myers Police Department said in an email, responding to a request for additional information.
