“There have been new developments in the case during the course of the day and we’re moving forward with those persons of interest,” Bill Bishop, chief assistant state attorney for Okaloosa County, said Thursday.

Law enforcement officials have reported progress in an expanding investigation into the Tuesday morning shooting of a 13-year-old at a school bus stop in Crestview.

“There have been new developments in the case during the course of the day and we’re moving forward with those persons of interest,” Bill Bishop, chief assistant state attorney for Okaloosa County, said Thursday.

Crestview Police Department spokesman Brian Hughes also acknowledged “some movement” in the investigation, adding “it’s nothing we can comment on today.”

Jerome Couch, a 15-year-old whose father is serving a life sentence for the 2012 murder of his estranged wife, is considered a “potential suspect” in the shooting case.

Couch was taken into custody Tuesday on charges of unlawful possession of a firearm by a minor, unlicensed carrying of a concealed weapon and violation of probation. He was the passenger in a stolen car driven by 13-year-old Velta Chesser.

Chesser was arrested around 8 a.m. Tuesday after being found on McClelland Street in Crestview near a broken down vehicle she’d allegedly stolen from her grandmother and driven around all night. The keys to the Chevy Impala were in her bra. Couch was identified as a passenger in that car by Okaloosa County Sheriff's Office.

Chesser and Couch were both registered students at Davidson Middle School, authorities said.

The 13-year-old victim, as yet unidentified in the shooting, was struck in the leg when shots were fired from a vehicle at about 6 a.m. Tuesday, records show. The Okaloosa Academy student was conscious and alert when authorities arrived on scene at the corner of Williams Avenue and Rayburn Street, and remains listed in fair condition at Sacred Heart Hospital in Pensacola.

Couch was reported Wednesday as being held at a Department of Juvenile Justice facility.
