Charmeca Mosley reportedly drove her car toward a crowd outside Atlantic's girls basketball game against Park Vista.

DELRAY BEACH — A Boynton Beach woman is accused of pulling a gun on multiple people outside the Atlantic High School girls basketball game Thursday night, according to Palm Beach County School District records.

Charmeca Mosley, 25 of Boynton Beach, was arrested on multiple weapons-related charges after officers found the gun and more than 100 bullets in her car. A judge ordered that she remain in the Palm Beach County Jail in lieu of $406,00 bail. She cannot have contact with any Palm Beach County schools.

Records indicate that a verbal dispute broke out during Atlantic's game against Park Vista High School and that two people involved were escorted out of the gymnasium. The argument carried over into the parking lot and a crowd gathered, witnesses told officers. Another person also may face a weapons charge related to the altercation, school district authorities said.

Shortly before 10 p.m. Mosley drove toward that group of people in the parking lot, almost hitting them, according to an arrest report. The crowd ran toward her car, and Mosley got out holding a gun. She pointed it at several people with whom she previously had been arguing and threatened to "air it out," meaning she would shoot, police said. It was not immediately clear whether she was involved in the initial altercation in the gymnasium.

A school police officer stopped her as she drove away in her gold-colored sedan. She admitted to being involved in an altercation and said she had a gun in her car, for which she claimed to have a concealed-carry permit. She agreed to allow officers to search her car, and they found the gun in her trunk.

The gun was loaded, officers noted, and lying near 124 rounds in the trunk.

In a message sent to parents Friday afternoon, principal Tara Dellegrotti said that another adult will face charges for reportedly having a knife during the incident. The details of that person's arrest were not immediately available. 

"School police believe that this is an isolated incident between the adult suspects," Dellegrotti said. "As this occurred after the game ended, there were very few witnesses." 

It was not immediately clear what time the game ended or how many people were in the parking lot at the time of the altercation. A school police officer wrote in Mosley's arrest report that "a large number of bystanders" were in the lot's entrance when the officer arrived to investigate the disturbance.

Mosley's arrest is the third arrest in 24 hours involving a gun on a Palm Beach County school's campus, according to jail records.

Martez Terrell Robinson, 18, was arrested Wednesday for reportedly having a loaded magazine and a pistol in his backpack, which was found at Riviera Beach Preparatory and Achievement Academy.

Princeley Jecrois, 18, of Lantana was arrested Wednesday after allegedly pointing a gun at a student at Boynton Beach High School in December. Records indicate that Jecrois is a former Boynton High student and that he previously threatened to shoot a student.

Both Robinson and Jecrois remained in custody late Friday.
