The girl and two 21-year-old women allegedly robbed the donut shop on PGA Boulevard at gunpoint on July 24.

PALM BEACH GARDENS — A 16-year-old Lake Park girl is being held in the Palm Beach County Jail without bond after police say she threatened an employee at gunpoint last month during a robbery of a Dunkin’ Donuts in Palm Beach Gardens.

Jalazia Smith is facing charges of robbery with a firearm and conspiracy to commit robbery with a firearm. She was initially arrested as a juvenile but the Palm Beach County State Attorney’s Office is charging her as an adult.

Two women — Kyrah Upperman, 21, of Riviera Beach, and Destinajah Williams, 21, of West Palm Beach — are also facing armed robbery charges in the case. They are being held without bond.

City police say Smith is the suspect on a surveillance video brandishing a handgun and pressing it against the body of a store employee during the robbery on July 24. The Dunkin’ targeted in the robbery is at the PGA Plaza, just off Prosperity Farms Road and PGA Boulevard.

Smith allegedly warned the employee: "If you make one sound it’s over."

A witness told police that Smith was wearing a red-and-white ski mask and a sports bra during the robbery.

The robbers allegedly took $467 from two cash registers and fled, the report said. Police later recovered $317. It’s unknown what happened to the remaining $150.

The other two women and Smith were arrested after police received a call about a suspicious car parked near the Dunkin’ that was robbed, the report said. The vehicle belonged to Williams, a former employee at the Dunkin’.

Masks used during the robbery were found in the car. The report does not state if a handgun was found.

After her arrest, Smith declined to speak with police and asked for an attorney. She also refused to give a DNA sample to authorities.
