AMSTERDAM — Police in the east of Amsterdam detained a 43-year-old female motorist on Monday night after she killed a thief who stole her bag. The 19-year-old victim was riding on a moped with a friend when they stopped beside the woman's car and opened the door to steal her bag. The thieves then tried to escape, but the woman reversed her car to cut them off, colliding with the scooter. After the collision, the car continued moving due to an "unknown" cause and the 19-year-old was wedged in between the car and a tree. He died at the scene....
