so my brother was in a car with his gf, and my brother was apparently driving. now my brothers license is suspended so hes not supposed to be driving. a cop went to go pull them over (for what im told a reason wasnt given why) and my brother got scared and decided to drive away. at some point he apparently parked the car at the house and went into the woods in hid. the cop saw someone run into the woods but wasnt sure who it was and didnt go look for him. he then tried to arrest his girlfriend for driving the car but had no proof it was her and couldnt do it, he also tried getting the mom to admitting it was her who was driving. Now like 3 days after the incident the cop came to my house and said he was looking for my brother and said his girlfriend said he was driving. hes apparently going to go to my brothers job tomorrow to talk to him. the cop doesnt have proof of who was driving but said he was trying to get an alibi from my brother to say he wasnt there and then i believe the cop said he was going to charge his girlfriend then. now my question is, because the cop doesnt know who was driving, what can happen to them?
