Vineland police arrested three people who allegedly robbed a city gas station with a 4-year-old boy inside the getaway car.

The suspects were identified because one of them had a friendly conversation with a city detective in front of the victim at the gas station two weeks ago.

The robbery occurred at 7:52 p.m. Thursday at the Gulf Gas Station at Weymouth Road and Delsea Drive. Police said Jason Brown, 28, and Craig Shugarts, 28, approached an attendant with a gun and demanded money. They then took the store’s cash register, containing $200, and drove off, police said.

But the attendant remembered Brown from when he made a purchase at the station two weeks ago and that he had chatted with Vineland Detective Ron DeMarchi, police said.

The suspects live in Pennsville, Salem County, and police went to the home they share on Dunlap Avenue with Holly Hall, 25. Police found the three suspects and Hall’s 4-year-old son inside a vehicle with a military style knife. They did not find the handgun.

After the investigation, police said Hall and her son were in the vehicle when the robbery occurred.

Police arrested Brown, Shugarts and Hall on charges of armed robbery and they were transported to Cumberland County Jail on $250,000 cash bail, police said. Additional charges are pending for endangering the welfare of a child and the state Division of Youth and Family Services have been contacted, police said.

Police recovered the cash register at Routes 40 and 55 in a wooded, swampy area. The stolen cash was not recovered, police said.
