PORT ST. LUCIE – A man who was shot in the head on May 2 in a car parked near Aspen Dental in the 1600 block of Northwest St. Lucie Boulevard, Port St. Lucie, died from his injuries on May 4, according to Port St. Lucie Police.

Antoine Myers, 19, of Georgia, was shot, along with a friend, Jermonti Johnson, also 19, at about 6:30 p.m., May 2. Johnson, who was shot in the abdomen, is being treated at a local hospital and is expected to recover, police said.

Two people involved in the shooting are in the St. Lucie County Jail as of May 4.

Martravious Aaron Blue Jr., 19, of Fort Pierce is in jail on a $1.3 million bond on two counts of premeditated murder and one count each of robbery with a firearm and grand theft.

Sharlett Nylah Key, 18, of Port St. Lucie is being held on a $75,000 bond for robbery with a firearm, tampering with evidence and accessory after the fact in a first-degree felony.

Police are still actively searching for a third suspect — Norrien Morris Casminski, 18, of Fort Pierce — on charges of murder, robbery with a firearm, and grand theft. Casminski has a prior criminal history that includes burglary, grand theft, and violation of probation, according to Chief Leo Niemczyk.

The incident started as a business transaction at a Walmart in Fort Pierce, after Myers and Johnson called the others on a cell phone and wanted them to buy and activate phones for them, Niemczyk said.

The suspects, after meeting up with the victims and driving them to Port St. Lucie, decided that they did not want to get involved and tried to steal money and phones from the victims before they were shot, Niemczyk said. The suspects then left the scene in a gold Chevy Cruze, he said.

Working throughout the night, officers were able to track the Cruze to the registered owner’s home, obtained search warrants and took Key and Blue into custody, Niemczyk said.

Police are searching for Casminski with the aid of the U.S. Marshals Service.

Next of kin for Myers has been notified, according to police reports.

“The Port St. Lucie Police Department extends its deepest condolences to the family and loved ones of Antoine Myers during this difficult time,” it was stated in a press release.

Anyone with information on this case is asked to call Port St. Lucie Police at 772-871-5000 or Treasure Coast Crime Stoppers at 1-800-273-TIPS.
