Police say Cory Gloe, who was a passenger in a car that was pulled over for speeding on Fallwood Parkway, was found to be in possession of a gravity knife and marijuana.
He was arraigned on weapon charges Wednesday. The driver was released on a desk appearance ticket.
Gloe admitted in Nassau County Court last week that he was racing another driver on May 10, 2014, when the other vehicle crashed, leading to the deaths of five teenager.
The families of victims -- 17-year-old Tristan Reichle, 18-year-old Jesse Romero, 14-year-old Carly Lonnborg, 15-year-old Noah Francis and 17-year-old Cody Talanian -- were outraged that Gloe was being given youthful offender status.
Gloe pleaded guilty to five counts of second-degree manslaughter, two counts of second-degree assault and five counts of criminally-negligent homicide, as well as other charges of reckless driving, reckless endangerment and leaving the scene of an accident. Sentencing was scheduled for May 20.
The new arrest was infuriating to the families, who were the first ones lining up at Gloe's arraignment Wednesday morning. But his defense lawyer suggested the latest case against Gloe is not what it seems.
"They're going to do the proper investigation, and I think at the end of the day, they're going to do what's right and just in this case," attorney Stephen LaMagna said.
The families disagreed.
"He has a blatant disregard for the law, and this just goes to prove character," said Mark McGlone, the uncle of one of the victims. "They're out there, they're speeding, just doing whatever they want. How many more lives do we need to lose before the system stops giving these slaps on the wrist?"
At Wednesday's arraignment in the latest case, the judge told Gloe it is likely his youthful offender status will be taken away when he goes for sentencing in the street racing case. And that means Gloe could spend up to 15 years in prison instead of six months.
The DA asked for $25,000 bail in the latest case, but the judge upped it to $50,000.
