Serial Killer Spreads Fear in France

French police are speculating that a serial killer is on the loose in Paris after four people were murdered with the same semiautomatic weapon in a suburb of the capital city. The murders, which have taken place over the past five months, have led police to increase their presence five-fold. The most recent, a 47-year-old woman, was killed Thursday. One suspect is being held in connection with the first killing, but no other arrests have been made.
