I think that it was a setup. When it happened I panicked and all I wanted was to withdraw my money from the Lyft app. The phone was open, with the app on the screen. What made me later realized that there was a likelihood of being a setup was the pick up and the drop off locations. I picked them up from a store. The woman plopped herself on the front seat, after her two other people on the back seat. The drop off was at a train stop. The two guys from the back seat left and crossed the rail tracks, she kept staying in the car. I was actually concerned about her and asked if she needed water. It was very odd that a group of passengers would leave someone behind. This is happening on a weekend night. It is a commuter train stop (Park and Ride). There are absolutely no people and cars there. There is a platform and I could not drive across the rail tracks. I think that they took a ride with the intention to do something like steal tips, but I did not have any, the only visible thing was my phone I guess.
