Sniper suspects on new murder charge

US authorities in Louisiana have charged the two Washington sniper suspects with another murder.

Meanwhile, officials in Alabama said they had also definitively linked the two men to a murder there.

John Allen Muhammad, 41, and John Lee Malvo, 17, are now charged with a month-long series of killings stretching from the Gulf Coast to the suburbs of the nation’s capital.

The two suspects face multiple state and federal counts in the Alabama and Louisiana cases, as well as the sniper spree that left 10 people dead and three others wounded in Maryland, Virginia and Washington DC.

They are also suspects in a February killing in Washington state.

Baton Rouge Police Chief Pat Englade issued first-degree murder warrants for Muhammad and Malvo after ballistics tests matched the rifle used in the sniper shootings to a September 23 killing and robbery in Baton Rouge, the Louisiana capital.
