LOS ANGELES (AP) — A one-day gun buyback program in Los Angeles brought in 2,037 firearms.

Mayor Antonio Villaraigosa's office says the weapons collected Wednesday included 901 handguns, 698 rifles, 363 shotguns and 75 assault weapons.

Long lines of cars and people showed up at two locations to exchange their weapons for supermarket gift cards of various values ranging up to $200 depending on the type of gun.

The buyback is usually held in May but was moved up in response to the Dec. 14 massacre of students and teachers at Sandy Hook Elementary School in Newtown, Conn.
