WASHINGTON (Reuters) - The United States on Sunday charged Jared Lee Loughner, the man suspected of killing six people and wounding a congresswoman in Arizona, with five criminal counts, including attempted assassination.
Loughner, 22, faces one count of attempted assassination of a member of Congress; two counts of killing an officer of the United States; and two counts of attempted killing of an officer of the United States.
The charges were filed in U.S. federal court in Phoenix. local time (4 p.m. EST/2100 GMT) on Monday, the Justice Department said.
Loughner is the main suspect in a shooting rampage that targeted U.S. Representative Gabrielle Giffords on Saturday. Six people were killed, including a U.S. judge, a Giffords aide and a 9-year-old girl. Giffords and 13 other people were wounded.
More charges against Loughner are possible, FBI Director Robert Mueller said at a news conference earlier in the day.

Investigators also found a document in a safe in Loughner’s residence that mentioned assassination plans, the filing said.
