PHILADELPHIA (CBS) — The 19-year-old man accused of carjacking a congresswoman last month in South Philadelphia is now facing federal charges. Investigators say Josiah Brown admitted he pointed a gun at Rep. Mary Gay Scanlon at FDR Park and demanded her keys on Dec. 22.

Brown and an accomplice drove away in the congresswoman’s Acura.

They were located a few hours later in New Castle, Delaware.

Brown is charged with carjacking and using a firearm during a crime of violence.
