ROME - Two American teenagers have been charged with the alleged killing of an Italian police officer following a drug deal gone wrong. The northern Californians refused to answer questions from the judge who nonetheless decided to keep them in custody. Italy is under shock at the violent killing of the officer.

The two teenagers were staying in a central Rome hotel where police found what they believe is the murder weapon, a long knife that had been hidden in the room's dropped ceiling along with bloody clothes believed to have been worn during the killing.

Nineteen-year-old Finnegan Lee Elder and 18-year-old Gabriel Christian Natale-Hjorth were high school classmates in the Bay Area of San Francisco and were at the end of their vacation in the Italian capital.

The man who suffered the theft reportedly called the police saying he had arranged a meeting with the young Americans to get his bag back. He said the Americans had demanded drugs and money to return the bag.

According to the authorities, two officers in plainclothes decided to go to the meeting set up with the young Californians instead of the alleged pusher.
