Malvo 'linked to four shootings'

US PROSECUTORS looking to bring a death penalty case against 17-year-old sniper suspect John Lee Malvo said fingerprints on the murder weapon and other evidence link him to three slayings and a fourth attack that left a man critically wounded.

Prosecutor Robert F Horan Jr also said Malvo tried to extort more than $10 million from authorities in

exchange for stopping last autumn's attacks, making his demands through a pair of notes and two phone calls.
