The 17-year-old son of PNB Rock murder suspect Freddie Trone has been arrested.

Police believe the youngster fired the gun that killed Rock while his dad drove the getaway car.  The Trones ultimately burned the car.

The father is still on the lam and considered armed and dangerous.

A woman named Shauntel Trone has also been arrested and booked for accessory to murder.  We don't know her exact relation to the other Trones.

Police also announced this afternoon that the Trone family was already in the parking lot of  Roscoe's Chicken & Waffles when Rock arrived, eliminating the possibility they got Rock's location because PNB's girlfriend posted their meal on social media.

But they did seem to know he was coming.
