Trooper Harrell was a five-year veteran who was assigned to Wilson County.
On Tuesday night, a relative of the trooper's told ABC11 that Harrell was "doing well" and continuing to recover after undergoing surgery.
Investigators arrested three people after Harrell's shooting. One of them, John Jones, is accused of attempted murder. A girlfriend of one of the other suspects said they were just in the wrong place at the wrong time.
The North Carolina State Highway Patrol said they received many questions about how to support Trooper Harrell, so a GoFundMe has been set up at the North Carolina State Employees Credit Union.
